Detailed Description
The present application is described in further detail below with reference to figures 1-7.
The embodiment of the application discloses a water quality detection device. Referring to fig. 1 and 2, the water quality detection device comprises a water quality detector 1, a detection ship body 2 and a driving mechanism 3, wherein the water quality detector 1 is installed on the detection ship body 2, and the water quality detector 1 is a commercially available portable unmanned ship detection instrument and is used for detecting water quality in real time; the detection ship body 2 is an unmanned ship, and the detection ship body 2 is in a cuboid structure. The driving mechanisms 3 are four, the four driving mechanisms 3 are respectively arranged at four corner positions of the detection ship body 2, and the detection ship body 2 is further provided with four power parts 4 which are respectively used for providing power for the four driving mechanisms 3 so as to drive the detection ship body 2 to advance through the four driving mechanisms 3. The distribution points of the four driving mechanisms 3 are rectangular, and the centers of the distribution points of the four driving mechanisms 3 coincide with the center of the detection hull 2.
The drive mechanism 3 comprises a drive shaft 31 and a plurality of drive blades 32 arranged around the drive shaft 31, the drive shaft 31 being rotationally connected to the test hull 2 via a transmission 5, and the transmission 5 being rotationally connected to the outer wall of the test hull 2. The power output end of the power member 4 is connected to the transmission member 5, the driving shaft 31 can swing relative to the detection hull, and the swinging direction of the driving shaft 31 is inclined downwards and faces to the stern of the detection hull 2. The four driving shafts 31 which correspond to the peripheral sides of the detection ship body 2 one by one are provided with four control pieces 21 which respectively control the four driving shafts 31 to swing, the power piece 4 is a driving motor and is installed on the inner side of the detection ship body 2, an output shaft of the power piece 4 penetrates out of the detection ship body 2 and is connected to the detection ship body 2 in a rotating mode, and the output shaft of the power piece 4 and the detection ship body 2 are arranged in a sealing mode through a rotating sealing ring.
Referring to fig. 1 and 2, further, adjacent driving blades 32 are spirally arranged around the corresponding driving shaft 31, and the spiral directions of the driving blades 32 of two adjacent driving shafts 31 are opposite, so that the vertical projections of the driving blades 32 of two adjacent driving shafts 31 are V-shaped, and the openings of the V-shapes face or are far away from the detection hull 2. In the embodiment of the present application, the V-shaped opening is disposed toward a direction away from the detection hull 2, so that when the four driving shafts 31 rotate, the driving blades 32 corresponding to two adjacent driving shafts 31 generate a driving force parallel to the axial direction of the driving shafts 31, and the directions of the driving forces are opposite. When the four driving shafts 31 are parallel to each other, the blade surfaces of the driving blades 32 on the four driving shafts 31 are crossed with each other, and the cross line is the center of the four driving shafts 31.
Referring to fig. 3, when in use, if a relatively complicated traveling path is encountered or a river or lake with relatively much interference needs to be detected, the driving blade 32 located on the upper side of the driving shaft 31 is located above the water surface, and when the driving blade 32 stirs water flow, a thrust F perpendicular to the surface of the driving blade 32 is generated, and at this time, the traveling direction of the detection ship body 2 is H; only the four power members 4 are needed to control the rotation direction L of the four driving shafts 31, when the rotation direction L of two adjacent driving shafts 31 is the same, the first driving force F1 of the driving force along the axial direction of the driving shaft 31 is opposite, and the second driving force F1 of the driving force perpendicular to the driving shaft 31 is generated in the same direction, at this time, F1 will balance each other, and push the detecting hull 2 to travel in the direction F2.
Referring to fig. 4, when the rotation directions L of two adjacent driving shafts 31 are opposite, the first split driving force F1 of the driving force in the axial direction of the driving shafts 31 is the same, and at the same time, the second split driving force F1 of the driving force perpendicular to the driving shafts 31 and opposite is generated, and at this time, F2 will be balanced with each other and at the same time, the detecting hull 2 is pushed to travel in the direction of F1; therefore, the driving force of advancing, retreating and lateral directions on the water surface can be realized by controlling the rotating directions L of the four driving shafts 31, so that when the driving device faces a relatively complex advancing path, the adaptability can be adjusted, and the flexibility in water quality detection is effectively optimized. In summary, the driving forces of the four driving mechanisms 3 can be controlled to be balanced with each other and to generate a thrust F in any direction parallel to the plurality of driving shafts 31, so that the detection hull 2 can be made to be able to rotate by itself while being able to travel in any direction.
In addition, when detection needs to be carried out in different ranges of the river channel, the posture of the ship body 2 can be adjusted and detected in real time so as to adapt to the state of river channel water flow; meanwhile, when rapid advancing is needed, only the control part 21 needs to control the driving shafts 31 to swing downwards, so that the driving blades 32 are completely immersed in water, at the moment, only thrust F of the four driving shafts 31 are required to incline upwards, and thrust F of the driving mechanism 3 positioned in the front part of the advancing direction is required to be larger than thrust F of the driving mechanism 3 positioned in the rear part, so that the bow of the detection hull 2 can be lifted, at the moment, the detection hull 2 can be lifted, so that the draft of the detection hull 2 can be effectively reduced, the resistance of water flow of a river channel or a lake is reduced, meanwhile, the driving force borne by the detection hull 2 can be increased, so that rapid advancing is realized, the rotating speeds of the driving shafts 31 along the advancing direction can be controlled, the rotating speeds of the two driving shafts 31 positioned at one end of the advancing direction of the detection hull 2 are larger than the rotating speeds of the other two driving shafts 31, so that one end of the detection hull 2 facing the advancing direction can be lifted, the water flow of the river channel is further reduced, and therefore, on the premise that the normal advancing speed is not influenced, water quality of the river channel can be relatively flexibly detected.
Referring to fig. 5 and 6, further, in order to control the swing of the driving shaft 31, the control member 21 is a hydraulic cylinder or an electric push cylinder, and in the embodiment of the present application, the control member 21 is an underwater electric push cylinder. The cylinder of the control member 21 is hinged to the detection hull 2, and the direction of oscillation of the control member 21 is arranged obliquely downwards and towards the stern of the detection hull 2, so that the direction of oscillation of the control member 21 is parallel to the direction of oscillation of the connected drive shaft 31.

Specifically, the inner wall of the control ring 22 and the outer wall of the driving shaft 31 are both provided with a connecting ring groove 221.

In the embodiment of the present application, the transmission member 5 includes a transmission shaft 51 and a plurality of transmission rods 52, the transmission shaft 51 is rotatably connected to the outer wall of the detection hull 2, and the output shaft of the power member 4 is fixedly connected to the transmission shaft 51. Specifically, a fixing ring 514 is sleeved outside one end, facing the detection ship body 2, of the transmission shaft 51, a connecting ring groove 221 is also formed in the inner wall of the fixing ring 514, an inner ring edge is also clamped in the connecting ring groove 221 and fixedly connected to the crossed cylindrical roller bearing 314 of the transmission shaft 51, an outer ring of the crossed cylindrical roller bearing 314 sleeved on the transmission shaft 51 is fixedly connected to the fixing ring 514, and the fixing ring 514 and the transmission shaft 51 are rotatably sealed through a rotary sealing ring, so that the transmission shaft 51 is relatively and stably connected to the detection ship body 2 in a rotating mode.
Referring to fig. 6, further, the transmission rods 52 are parallel to the transmission shaft 51, the transmission shaft 51 is provided with a plurality of insertion holes 515 corresponding to the plurality of transmission rods 52, and the plurality of transmission rods 52 respectively penetrate through the plurality of insertion holes 515 in a one-to-one correspondence and are connected in a sliding manner, so that the transmission rods 52 are inserted into and connected in the transmission shaft 51 in a sliding manner. Wherein a plurality of transmission rods 52 are arranged around the central axis of the transmission shaft 51.

The plurality of driving blocks 53 are respectively engaged and slidably connected to the plurality of driving grooves 312 in a one-to-one correspondence.
When the angle of the driving shaft 31 relative to the transmission shaft 51 is changed, the transmission block 53 can slide relative to the transmission groove 312 to perform adaptive adjustment without bending the transmission rod 52 because the driving shaft 31 swings.
Referring to fig. 6, a transmission pipe 511 is fixedly connected to one end of the transmission shaft 51 far away from the detection hull 2, and the transmission pipe 511 and the transmission shaft 51 are arranged on the same central axis.

When the device is used, the driving shaft 31 can swing relative to the detection hull 2, and the driving shaft 31 can swing relative to the transmission shaft 51 at the moment, so that the device can adapt to the angle change between the driving shaft 31 and the transmission shaft 51 through the sliding of the transmission rod 52 relative to the transmission shaft 51; meanwhile, the driving shaft 31 can be shifted to rotate through the transmission rod 52, and in the rotating process of the driving shaft 31, the driving shaft 31 can be limited through the transmission pipe 511, so that the driving shaft 31 is relatively stable in rotation; in addition, the plurality of transmission rods 52 can be isolated from the external water flow by the transmission pipes 511, so that the influence of the arrangement of the transmission rods 52 on the detection of the resistance when the ship body 2 travels is reduced; meanwhile, compared with a universal coupling, the driving ball 311 can be limited through the transmission pipe 511, and the swing of the driving shaft 31 during rotation can be effectively reduced under the condition that the rotation of the driving shaft 31 is not interfered; in addition, the two ends of the connecting shaft do not need to be additionally arranged to be universally hinged to the driving shaft 31 and the output end of the power part 4, the space required by installation can be further reduced, and the resistance generated during traveling is reduced.
