Fig. 1 is a schematic structural view of a water depth measuring device according to an embodiment of the present invention; fig. 2 is a schematic view of the water depth measuring apparatus shown in fig. 1, viewed from below. As shown in fig. 1-2, the present invention provides a device for measuring depth of a body of water, comprising:
a submerged part 10 submerged deep in the water area and having a corresponding remote control part controlling the traveling direction and the traveling route;
a water floating part floating on the water surface;
a hand-held control unit 1 for hand-held control by a measurer standing on the shore;
the measuring rope 2 extends out of the handheld control part 1, penetrates through the water floating part and is connected with the submerged part 10;
the water floating part floats on the water surface along with the advancing of the underwater part 10, so that the water floating part and the underwater part 10 are kept in the same vertical direction.
In the device, one end of the measuring rope 2 is fixedly connected to the diving part 10, the other end of the measuring rope is coiled on the handheld control part 1, and the measuring rope 2 penetrates through the floating part and can be drawn back and forth. When the diving part 10 dives under the water, the measuring rope 2 is gradually untied by the handheld control part 1, passes through the floating part and then enters the underwater, and the floating part floats on the water surface after being influenced by the buoyancy. When the submerged part 10 reaches the deepest part of the water bottom, the vertical distance between the floating part and the submerged part 10 is the depth of the water area, and can be marked by the length of the measuring rope 2 entering the water. This eliminates the need to measure the water depth directly at the water area, which can be transferred to the length of the measuring line 2 and thus be measured from the retrieved measuring line 2.
The device for measuring the depth of the water area provided by the invention has the advantages that the diving part 10 is buried in the water bottom, one end of the measuring rope 2 is driven to reach the water bottom, the measuring rope 2 penetrates through the floating part floating on the water surface, and the distance between the diving part 10 and the floating part, namely the depth of the water area, of the measuring rope 2 is obtained. Thus, the measurer can know the depth of the water area by reading the water inlet distance of the measuring rope 2.
The submersible 10 may be embodied as a submersible, which refers to a mobile deep diving apparatus with underwater viewing and working capabilities. Can be a manned submersible or an unmanned submersible. The remote control corresponding to the submersible 10 is typically its own remote control that controls the travel path and direction of the vehicle.
In order to facilitate rough estimation of the length of the measuring rope 2, knots 3 can be arranged on the measuring rope 2 at every other meter position, and when the water depth does not need to be accurately measured, the number of the knots 3 can be roughly estimated, so that the approximate position of the water depth can be judged. Is more convenient and faster.
The hand-held control part 1 can be a paying-off device and is used for controlling the winding and unwinding of the measuring rope 2. Can be a hand-operated paying-off device or an electric paying-off device. The control of the measuring rope 2 by a measurer can be mainly facilitated.
The floating portion floats on the water surface and can float and move to the position right above the diving portion 10 according to the specific orientation of the diving portion 10.
Referring to fig. 1, the floating part comprises a swim ring 4 and a floating plate 6 arranged below the swim ring 4, and a support plate 18 is embedded and fixed in the center of the inner circle of the swim ring 4.
The swim ring 4 is full of air and has buoyancy, so that the swim ring can float on the water surface. In order to ensure that the swim ring 4 can be kept in a horizontal state, the floating plate 6 is arranged below the swim ring 4, so that the swim ring 4 can be prevented from overturning to influence the measurement effect. Because the central part of the swim ring 4 is hollow, in order to ensure that the measuring rope 2 can just penetrate through the center of the swim ring 4 and the floating plate 6, a supporting plate 18 is submerged and fixed at the inner circle center of the swim ring 4. And a hole for accommodating the measuring rope 2 to pass through is arranged at the centers of the supporting plate 18 and the floating plate 6.
Referring to fig. 1, the floating structure further includes a stabilizing portion disposed below the floating portion to maintain stability of the floating portion, and the stabilizing portion includes a bottom plate 8 disposed below the floating plate 6 to maintain stability and a stabilizing bracket 7 connecting the floating plate 6 and the bottom plate 8.
In order to further ensure the stability of the water floating part and simultaneously ensure that the water floating part is always kept above the diving part 10, a stabilizing part is arranged below the water floating part. The firm portion includes bottom plate 8 and stabilizing support 7, keeps one section distance between bottom plate 8 and kickboard 6, and a plurality of stabilizing support 7 then set up between bottom plate 8 and kickboard 6, makes to form holistic water-floating portion and firm portion remain stable, can not turn on one's side. Meanwhile, the stabilizing part is arranged below the floating part, so that severe deviation can not occur when the position of the floating part is adjusted, and the centering adjustment of the floating part and the diving part 10 is influenced.
Referring to fig. 1, a first through hole for accommodating the measuring string 2 is formed in the center of the bottom plate 8, and a plurality of first elastic pieces 12 with downward inclined centers are arranged at the first through hole. A second through hole for accommodating the measuring rope 2 to penetrate is formed in the center of the supporting plate 18, and a plurality of second elastic sheets 13 with downward inclined centers are arranged at the second through hole.
The measuring rope 2 extends out of the handheld control part 1, sequentially passes through the second through hole of the supporting plate 18, the floating plate 6 and the first through hole of the bottom plate 8, and is further connected with the diving part 10. In order to ensure the accuracy of the measuring result, the measuring string 2 can smoothly move towards the diving part 10 according to the traction force of the diving part 10, but cannot reversely move towards the hand-held control part 1 during the measuring process. Therefore, the first elastic sheet 12 and the second elastic sheet 13 are respectively arranged at the first through hole and the second through hole, and the first elastic sheet 12 and the second elastic sheet 13 with downward inclined centers are used for ensuring that the measuring rope 2 can pass through the first through hole and the second through hole in one direction in the measuring process. When the whole measuring device finishes measuring and withdrawing, a measurer only needs to pull the measuring rope 2 slightly and forcefully in the direction of the handheld control part 1, and then the measuring rope 2 can be withdrawn and wound on the handheld controller. At this time, the first elastic piece 12 and the second elastic piece 13 are inclined upward in the center due to elasticity. When the submersible vehicle is used next time, the centers of the first elastic sheet 12 and the second elastic sheet 13 are inclined downwards only by pulling the measuring rope 2 slightly and forcefully towards the direction of the submersible vehicle.
Referring to fig. 1, the top of the supporting plate 18 is provided with a buckle 14 with an open upper end, and the measuring string 2 is limited on the buckle 14 and can be drawn back and forth.
For preventing that whole flotation portion from taking place to rotate on the surface of water, influence measurement accuracy, this application has set up buckle 14 in backup pad 18, and measuring rope 2 is spacing on buckle 14 and can make a round trip to twitch, because measuring rope 2 is controlled by handheld control portion 1, consequently, bears this buckle 14's flotation portion and can not take place to rotate yet.
Referring to fig. 1, a plurality of floating propellers 5 are uniformly arranged around the swim ring 4. The tail end of the submerged part 10 is provided with a submerged propeller 9.
The submersible 10 is powered by the submersible propeller 9 when submerged and when the orientation is adjusted at the bottom. The engine rotation power of the submersible 10 is converted into the propelling force for propelling the submersible 10 by means of the rotation of the blades of the submersible propeller 9 in the water. The floating part is always kept above the diving part 10 for adjustment and needs to move on the water surface along with the floating part, and the floating propeller 5 provides power for the floating part.
Referring to fig. 1 and 2, a first infrared ray emitter 15 is disposed at a lower end of the bottom plate 8, a second infrared ray emitter 11 is disposed at a top end of the submersible 10, and the first infrared ray emitter 15 and the second infrared ray emitter 11 are used for ensuring that the bottom plate 8 and the submersible 10 are kept in a centered state.
The first infrared radiator emits infrared light directly below, the second infrared radiator emits infrared light directly above, and when the two infrared lights coincide, it means that the first infrared radiator is directly above the second infrared radiator, that is, that the float part is directly above the dive part 10.
The infrared ray radiator basically comprises a transmitting end, a receiving end, a light beam intensity indicator lamp, an optical lens and the like. The detection principle is that infrared rays emitted by an infrared light emitting diode are focused by an optical lens, so that the rays are transmitted to a long distance, and finally the rays are received by a photosensitive transistor at a receiving end.
Referring to fig. 2, an infrared sensor 16 for detecting whether fish shoal exists around is provided at the bottom end of the submersible 10.
If fish schools are present around the submersible, the measurement is easily disturbed. Therefore, in order to avoid the fish school from interfering with the measurement, when the infrared sensor 16 senses the existence of the fish school, the submersible can be controlled to move to other nearby positions or the measurement can be carried out after the fish school is scattered.
Referring to fig. 2, the bottom end of the submersible 10 is further provided with a camera 17 or an infrared scanner for scanning and imaging the underwater topography.
The camera 17 or the infrared scanner is arranged at the bottom end of the underwater part 10, so that the underwater part 10 can be judged whether to submerge into the deepest part underwater or not, the bottom topography can be scanned and imaged, the submerging depth and the scanning ground can be obtained, and the bottom topography of the water area can be accurately determined.
The invention has simple structure, convenient carrying and safe operation, and has corresponding function and value in the engineering fields of surveying and mapping, water conservancy, geology and the like.
The invention also provides a water depth measuring method, which adopts the measuring device to send the measuring device into the water of the measured point, adopts a remote control part to control the submersible vehicle to submerge to the deep underwater until the submerged part 10 submerges to the deepest part and stops, and the length of the measuring rope 2 between the submerged part and the submerged part 10 is the water depth of the measured point.
