Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0053] Please also read Figures 1 to 9 The riverbed sediment ecological restoration device provided in the present application is now described. The riverbed sediment ecological restoration device proposed in the present application comprises a hull 1, a guide column 2, a lifting plate 3 and a spray gun body 4.

[0054] The hull 1 is used for traveling on the water surface, and has a reserved hole 11 penetrating in the up-down direction; usually, the reserved hole 11 is located in the middle of the hull 1 and avoids the position of the floating part on the lower side of the hull 1.

[0055] The guide column 2 is a hollow tube structure with two ends opened. It is detachably connected to the upper side of the hull 1 and is coaxially connected to the reserved hole 11, that is, the axial direction of the guide column 2 is parallel to the up and down direction.

[0056] The lifting plate 3 is disposed in the guide column 2 and is slidably connected to the inner wall of the guide column 2 in the up-down direction. The lifting plate 3 is transmission-connected to a linear driving member 5 for driving the lifting plate 3 to reciprocate in the up-down direction.

[0057] The spray gun body 4 is used to spray the repair liquid outward. It is arranged on the lower side of the lifting plate 3 and is connected to the lifting plate 3 through a number of connecting rods 41. The spray gun body 4 also includes a water tank 6 fixedly arranged on the upper side of the hull 1, and a hose 61 connected to the water tank 6 and the spray gun body 4. When the spray gun body 4 is started, the repair liquid in the water tank 6 can enter the spray gun body 4 through the hose 61 and be output to the outside through the liquid outlet of the spray gun body 4.

[0058] In the embodiment of the present application, the lifting plate 3 can be moved in the up and down directions through the linear driving component 5, thereby driving the spray gun body 4 to repeatedly insert or withdraw from the bottom mud; on this basis, through the spraying action in the spray gun body 4, the repair liquid in the water tank 6 can enter the spray gun body 4 through the hose 61.

[0059] That is, when the spray gun body 4 is inserted into the bottom mud, the water storage tank 6 can input the repair liquid to the spray gun body 4 through the hose 61 , so that the repair liquid is sprayed into the bottom mud under the action of the spray gun body 4 .

[0060] Compared with the prior art, the riverbed sediment ecological restoration device provided in this embodiment can input the restoration liquid into the sediment, thereby ensuring the effect of the restoration liquid and further ensuring the ecological restoration effect of the riverbed sediment.

[0061] In order to make the riverbed sediment ecological restoration device proposed in the present application applicable to water systems of different sizes, the action system of the spray gun body 4 can form a multi-point data sharing control function with a third-party platform through a communication protocol.

[0062] In some embodiments, Figure 2 As shown, the aforementioned riverbed sediment ecological restoration device also includes a top cover 7, an infrared ranging component 8 and a controller 9.

[0063] The top cover 7 is detachably connected to the upper end of the guide column 2 so as to be suitable for closing the upper end opening of the guide column 2 and forming a relatively sealed and light-proof space between the top cover 7 and the lifting plate 3 .

[0064] The infrared distance measuring member 8 is disposed between the top cover 7 and the lifting plate 3 , and is used to measure the distance between the top cover 7 and the lifting plate 3 .

[0065] The controller 9 is electrically connected to the signal output module of the infrared distance measuring component 8 and the control module of the linear driving component 5 .

[0066] Among them, the controller 9 can preset a first value and a second value, and the first value is greater than the second value; when the linear driving component 5 drives the lifting plate 3 to move, the value output by the infrared ranging component 8 is less than or equal to the first value and greater than or equal to the second value.

[0067] By adopting the above technical solution, when the controller 9 and the linear drive component 5 are both in the starting state and the value output by the infrared ranging component 8 is equal to the second value or the first value, the controller 9 can control the linear drive component 5 to start in reverse, so that the lifting plate 3 is transformed from the descending state to the ascending state, or the lifting plate 3 is transformed from the ascending state to the descending state, so that the spray gun body 4 repeatedly enters and exits the bottom mud.

[0068] It should be noted that the controller 9 used in the embodiment of the present application is programmable; in actual use, the operation mode of the controller 9 can be preset by programming to perform cyclic operation under the same operation logic and to perform reciprocating injection of the bottom mud repair liquid at a preset depth. In addition, through 5G data networking or other remote sensing data modes, remote control and data upload of the controller 9 and the linear drive member 5 can be achieved.

[0069] In some embodiments, Figure 7 As shown, the linear driving member 5 includes a rotary motor 51 and a driven nut 52 .

[0070] The rotating motor 51 is fixedly arranged on the upper side of the top cover 7, and its power output axis is parallel to the up and down direction; a driving screw 511 is coaxially connected to the power output end of the rotating motor 51, and the driving screw 511 is rotationally connected to the top cover 7, and the driving screw 511 penetrates the top cover 7 and extends into the guide column 2.

[0071] The driven nut 52 is fixedly connected to the lifting plate 3 and is threadedly connected to the driving screw 511 .

[0072] When the rotating motor 51 is started, the active screw 511 rotates at the same time, so that the driven nut 52 rotates relative to the active screw 511; since the driven nut 52 is connected to the lifting plate 3 and the lifting plate 3 cannot rotate, the driven nut 52 will rise and fall under the influence of the screwing force between it and the active screw 511.

[0073] It should be noted that the rotating motor 51 used in the embodiment of the present application is a digital motor, which can accurately control the number of rotations, so that the riverbed mud ecological restoration device proposed in the present application has the ability to accurately control the output point of the restoration liquid.

[0074] In some embodiments, Figure 5 As shown, the upper end of the guide column 2 has a first protrusion 21 extending outward, and the first protrusion 21 has a positioning hole 211 penetrating in the up-down direction; the outer peripheral wall of the top cover 7 has a second protrusion 71 extending outward, and the second protrusion 71 has a positioning hole 711 penetrating in the up-down direction and suitable for being coaxially connected with the positioning hole 211.

[0075] A locking bolt 72 is provided between the first protrusion 21 and the second protrusion 71 , and a docking nut 721 is threadedly connected to the locking bolt 72 .

[0076] By adopting the above technical solution, when the positioning hole 211 and the alignment hole 711 are coaxially connected, the locking bolt 72 is suitable for being inserted into the mutually connected positioning hole 211 and the alignment hole 711, so that the head of the locking bolt 72 and the docking nut 721 respectively abut against the first protrusion 21 and the second protrusion 71, thereby limiting the top cover 7 from being separated from the guide column 2.

[0077] In some embodiments, Figure 1 , Figure 2 and Figure 6As shown, the hose 61 passes through the lifting plate 3 and the top cover 7 and extends out. The aforementioned riverbed mud ecological restoration device also includes a first fixed pulley 10, a second fixed pulley 20 and a third fixed pulley 30.

[0078] The first fixed pulley 10 is rotatably disposed on the upper side of the top cover 7 , and is located on the upper side of the top cover 7 .

[0079] The second fixed pulley 20 is rotatably disposed on the guide column 2 , and is arranged in parallel with the first fixed pulley 10 in the horizontal direction, and is located outside the top cover 7 .

[0080] The third fixed pulley 30 is rotatably disposed on the upper side of the hull 1, and is arranged in parallel with the second fixed pulley 20 in the up-and-down direction.

[0081] In actual use, the extended portion of the hose 61 is successively arranged through the first fixed pulley 10 , the second fixed pulley 20 and the third fixed pulley 30 , and the portion of the hose 61 extending through the third fixed pulley 30 is connected to the water storage tank 6 .

[0082] In some embodiments, Figure 1 and Figure 3 As shown, there are multiple fixing members 40 arranged at intervals between the third fixed pulley 30 and the water tank 6, and each fixing member 40 is fixedly connected to the upper side of the hull 1; there is a sliding member 50 for abutting the hose 61 between each group of two adjacent fixing members 40, and the sliding member 50 is slidably connected to the upper side of the hull 1, and its sliding direction is perpendicular to the arrangement direction of the fixing members 40; and there is an elastic member 60 between each sliding member 50 and the upper side of the hull 1.

[0083] The reason for providing a plurality of sliding members 50 is to improve the straightening effect of the sliding member 50 on the hose 61 , thereby reducing the space occupied by the sliding member 50 along the sliding direction thereof.

[0084] By adopting the above technical solution, when the spray gun body 4 moves downward, the sliding member 50 slides and the elastic member 60 elastically deforms; when the spray gun body 4 moves upward, the sliding member 50 slides and the elastic member 60 recovers its deformation, so that the hose 61 between the first fixed pulley 10 and the spray gun body 4, between the first fixed pulley 10 and the second fixed pulley 20, and between the second fixed pulley 20 and the third fixed pulley 30 can all remain in a straight state.

[0085] In some embodiments, Figure 3 As shown, the upper side of the hull 1 has a plurality of slide grooves 12, and a plurality of sliding members 50 are slidably connected in the plurality of slide grooves 12 in a one-to-one correspondence; the elastic member 60 is a spring arranged in the slide groove 12 and connected to the inner wall of the slide groove 12 and the sliding member 50.

[0087] Among them, the third protrusion 22 has a hole structure that penetrates along the up and down directions and is suitable for inserting the fixing bolt 221; in actual use, the fixing bolt 221 and the lower side of the embedding groove 131 are threadedly connected, and the head of the fixing bolt 221 abuts against the upper side of the third protrusion 22 to achieve a fixed connection between the guide column 2 and the hull 1.

[0088] In some embodiments, Figure 6 and Figure 7 As shown, the inner wall of the guide column 2 has a plurality of strip grooves 23 arranged at intervals along its circumference, and each strip groove 23 extends in the up-down direction and the upper end passes through the upper end surface of the guide column 2; the outer peripheral wall of the lifting plate 3 has a plurality of fourth protrusions 31 suitable for slidingly engaging in the plurality of strip grooves 23 in a one-to-one corresponding manner.

[0089] The sliding connection between the lifting plate 3 and the guide column 2 is achieved through the sliding connection between the fourth protrusion 31 and the strip groove 23 .

[0090] In some embodiments, Fig. 9 As shown, the lower end of the spray gun body 4 adopts a conical structure, and the liquid outlet part of the spray gun body 4 is located on the conical surface.

[0091] Among them, the conical structure can make it easier to break through and insert into the bottom mud; after the spray gun body 4 is inserted into the bottom mud, since the liquid outlet parts are all on the conical surface, the liquid output by the spray gun body 4 can smoothly enter the bottom mud.

[0092] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
