DETAILED DESCRIPTION

[0052] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0053] Please refer to Figures 1 to 12 , the detachable injection device based on the microbial dredging technology provided by the present application will be described. The detachable injection device based on the microbial dredging technology proposed by the present application comprises a hull 1, a mounting seat 2 and a spray gun body 3.

[0054] The hull 1 is used for driving on the water surface, and has a reserved hole 11 penetrating in the up-down direction and a filling piece 12 slidingly inserted into the reserved hole 11 in the up-down direction; it should be noted that when the filling piece 12 is inserted into the reserved hole 11 from top to bottom, the filling piece 12 is supported and cannot continue to move downward.

[0055] The mounting seat 2 is arranged on the lower side of the filling piece 12, and is drivingly connected with a lifting driving assembly 4 for driving the mounting seat 2 to move in the up-down direction.

[0056] The spray gun body 3 is arranged on the lower side of the mounting seat 2, and is connected with the mounting seat 2 through a plurality of groups of positioning structures 5; when the spray gun body 3 needs to be disassembled, each group of positioning structures 5 needs to be adjusted to ensure the structural stability of the spray gun body 3.

[0057] It should be noted that the stability of the spray gun body 3 is directly proportional to the number of positioning structures 5, while the disassembly and assembly efficiency of the spray gun body 3 is inversely proportional to the number of positioning structures 5. In this embodiment, the positioning structures 5 are usually designed to be easy to operate manually and less affected by the environment, so as to find a balance between the stability and disassembly and assembly efficiency of the spray gun body 3, thereby making this product more suitable for actual working conditions.

[0058] The spray gun body 3 also includes a water tank 6 fixedly installed on the upper side of the hull 1, and a hose 61 connected to the water tank 6 and the spray gun body 3; when the spray gun body 3 is started, the sludge removal fluid inside the water tank 6 can be input through the hose 61 and finally output through the water outlet on the surface of the spray gun body 3.

[0059] In this embodiment, the lifting drive assembly 4 can drive the mounting base 2 to move upward, so that the mounting base 2 lifts the filler 12 to move upward, and the spray gun body 3 moves to the upper side of the hull 1 through the reserved hole 11, thereby facilitating manual adjustment of the positioning assembly and achieving the technical purpose of separating the spray gun body 3 and the mounting base 2.

[0060] The detachable injection device based on microbial dredging technology provided in this embodiment, compared with the prior art, facilitates the disassembly and installation of the spray gun, reduces the time spent on disassembling and assembling the spray gun, and ensures the overall efficiency of the injection process.

[0061] In some embodiments, such as Figure 5 , Figures 8 to 10 As shown, the positioning structure 5 includes a positioning rod 51 and an alignment cylinder 52.

[0062] The positioning rod 51 is fixedly connected to the upper end of the spray gun body 3, and its axis is parallel to the vertical direction. The upper end of the positioning rod 51 has a protrusion 511 extending outward along its radial direction.

[0063] The alignment cylinder 52 is disposed on the lower side of the mounting base 2, its axis is parallel to the vertical direction, and it is rotatably connected to the mounting base 2 in the vertical direction. In this embodiment, the alignment cylinder 52 has a cylindrical cavity 521 that extends vertically and is suitable for the insertion of the positioning rod 51. On the inner wall of the cylindrical cavity 521, there is a first guide groove 522 that extends vertically and is suitable for the insertion of the protrusion 511. The upper end of the first guide groove 522 has a second guide groove 523 that extends circumferentially along the alignment cylinder 52 and is suitable for the insertion of the protrusion 511.

[0064] By adopting the above technical scheme, when the spray gun body 3 needs to be installed, the spray gun body 3 needs to be manually moved to the state that the positioning rod 51 is inserted into the alignment barrel 52, the protrusion 511 is moved from the lower end of the first guide groove 522 to the upper end of the first guide groove 522 (that is, the intersection of the first guide groove 522 and the second guide groove 523), and at this time, the alignment barrel 52 can also be considered to be rotated, so that the protrusion 511 is screwed into the second guide groove 523.

[0065] When the protrusion 511 is in the second guide groove 523, the lower side of the protrusion 511 can abut against the inner wall of the second guide groove 523, so as to limit the downward movement of the positioning rod 51 relative to the alignment barrel 52, thereby achieving the detachable connection of the spray gun body 3 and the mounting seat 2.

[0066] In some embodiments, as shown in Figure 8 The alignment barrel 52 has a swing arm 9 extending radially outward therefrom, and the swing end of the swing arm 9 has a through hole 91 extending in the up-down direction.

[0067] In actual use, with the swing of the alignment barrel 52, the through hole 91 moves around the central axis of the alignment barrel 52; when the positioning structure 5 has multiple groups, by rotating multiple alignment barrels 52, the corresponding multiple through holes 91 can be coaxially communicated.

[0068] The mounting seat 2 further comprises a fixing nut 7 and a locking bolt 71.

[0069] The fixing nut 7 is fixedly connected to the lower side of the mounting seat 2; when the alignment barrel 52 is rotated to the state that the protrusion 511 abuts against the inner wall of the second guide groove 523 (the spray gun body 3 and the mounting seat 2 are connected), the fixing nut 7 is coaxially communicated with the corresponding through hole 91.

[0070] The locking bolt 71 is adapted to be inserted into the through hole 91 from bottom to top, and is adapted to be threadedly connected with the fixing nut 7, so as to limit the swing of the swing arm 9 and the rotation of the alignment barrel 52, and improve the stability of the overall structure.

[0071] In some embodiments, as shown in Figure 8 The lower side of the mounting seat 2 has a clamping groove 21 adapted to embed the fixing nut 7, and the groove bottom of the clamping groove 21 has a recess 22 adapted to insert the locking bolt 71.

[0072] By adopting the above technical scheme, the clamping groove 21 realizes the sinking installation of the fixing nut 7, the recess 22 provides a margin for the screwing of the locking bolt 71, and the connection strength of the fixing nut 7 and the locking bolt 71 is ensured.

[0073] In some embodiments, as shown in Figure 5 and Figure 8As shown, the positioning structure 5 has two groups; in this embodiment, the two groups of positioning structure 5 are arranged side by side along the horizontal direction, and the two groups of positioning structure 5 are arranged around the fixed nut 7.

[0074] Wherein, when both swing arms 9 swing to the corresponding through hole 91 and the fixed nut 7 coaxially communicate, the locking bolt 71 is suitable for passing through the two through holes 91 and being threadedly connected with the fixed nut 7.

[0075] In some embodiments, as shown in the drawings, Figure 7 As shown, the lifting driving assembly 4 includes a lifting seat 41, a transmission nut 42 and a transmission screw 43.

[0076] The lifting seat 41 is arranged on the upper side of the filling piece 12, and it is slidably connected with the hull 1 along the up-down direction through the guide structure 8; the lower side of the lifting seat 41 has a connecting rod 411 extending downward, penetrating through the filling piece 12 and extending out, and the lower end of the connecting rod 411 is connected with the mounting seat 2; wherein, due to the presence of the connecting rod 411, the lifting seat 41 and the mounting seat 2 move synchronously.

[0077] The transmission nut 42 is fixedly arranged on the lifting seat 41, and its axial direction is parallel to the up-down direction.

[0078] The transmission screw 43 is arranged on the upper side of the hull 1, and it is threadedly connected with the transmission nut 42, and it is rotationally connected with the hull 1 along the up-down direction.

[0079] Wherein, the transmission screw 43 is drivingly connected with a rotating motor 431.

[0080] By adopting the above technical scheme, when the rotating motor 431 is started, the transmission screw 43 is forced to rotate to drive the lifting seat 41 to move along the up-down direction through the transmission nut 42, and then drive the mounting seat 2 to move synchronously through the connecting rod 411.

[0081] In some embodiments, as shown in the drawings, Figure 12 The guide structure 8 includes a directional hole 81 and a guide rod 82.

[0082] The directional hole 81 is arranged on the lifting seat 41, and it penetrates the lifting seat 41 along the up-down direction.

[0083] The guide rod 82 is fixedly arranged on the upper side of the hull 1, its axial direction is parallel to the up-down direction, and it is inserted into the directional hole 81.

[0084] It should be noted that the guide rod 82 cooperates with the aforementioned transmission screw 43 to limit the rotation of the lifting seat 41.

[0085] In some embodiments, as shown in the drawings, Figure 1 and Figure 6As shown in the drawings, the hose 61 penetrates the filler 12 in the up-down direction and extends out, and the detachable filling device provided in the embodiments of the present application further comprises two fixed pulleys 13.

[0086] The two fixed pulleys 13 are arranged on the upper side of the filler 12 in the arrangement direction of the reserved hole 11 and the water tank 6, and each fixed pulley 13 is rotationally connected with the filler 12.

[0087] By adopting the above technical solution, the extended part of the hose 61 passes through the two fixed pulleys 13 and is connected with the water tank 6 in sequence, so that the hose 61 is oriented and direct contact between the hose 61 and the filler 12 is avoided to prevent damage.

[0088] In some embodiments, as shown in Figure 7 and Figure 11 the lower side of the filler 12 has a plurality of insertion grooves 121, and the upper side of the mounting seat 2 has a plurality of insertion rods 23 corresponding to the plurality of insertion grooves 121.

[0089] By adopting the above technical solution, when the mounting seat 2 moves upward to abut against the filler 12, the plurality of insertion rods 23 are inserted into the plurality of insertion grooves 121 in one-to-one correspondence, so as to limit the movement of the filler 12 relative to the mounting seat 2 in the horizontal direction, thereby preventing the filler 12 and the mounting seat 2 from being separated.

[0090] In some embodiments, as shown in Figure 6 the two sides of the reserved hole 11 in the front-rear direction of the ship body 1 are inclined surfaces, and the inclined surfaces are inclined inward from top to bottom.

[0091] The filler 12 is matched with the reserved hole 11; specifically, the front and rear ends of the filler 12 are inclined surfaces, and the inclined surfaces are inclined inward from top to bottom.

[0092] By adopting the above technical solution, when the filler 12 is embedded in the reserved hole 11, the front and rear sides of the filler 12 are respectively supported on the two inclined surfaces, so as to limit the filler 12 from continuing to move downward relative to the ship body 1.

[0093] The above is only a preferred embodiment of the present application, and does not limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
