Description
Technical field
The utility model belongs to underwater survey equipment technical field, is specifically related to a kind of anti-lost sonar instrument used under water.
Background technology
Conventional sonar instrument is connected with traction cable by connecting pin; when sonar instrument works under water; often can encounter various discards under water; barrier; score a goal ... owing to being subject to the effect of external force; come off after causing the connecting pin bending between sonar instrument and traction cable; after connecting pin is bending; the relieving ring of both sides is at all inoperative; sometimes, after sonar instrument is suspended to barrier, result pulls out light together with entire volume traction cable, sinks under water; there is regular loss in sonar instrument thereupon, and sonar instrument loss can cause huge economic loss under water.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and aims to provide a kind of structure simple, anti-lost sonar instrument easy to use.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-lost instrument of sonar under water, comprise body, Sonar Signal generator is provided with in described body, the front end of described body is provided with towing device, described towing device comprises the first link and first and U-shapedly drags button, first link has the first through hole, first U-shaped dragging on the both sides connecting rod of button openend all has the first mounting hole, described first through hole is connected by installing the first bolt with in two the first mounting holes, the thread end of the first bolt is by two the first bolt-lockings, described first U-shaped drag to buckle be connected with traction cable, the rear end of described body is provided with loss prevention device, described loss prevention device comprises the second link and second and U-shapedly drags button, second link has the second through hole, the second U-shaped both sides connecting rod dragging button to drag button openend has the second mounting hole, described second through hole is connected by installing the second bolt with the second U-shaped dragging in button, the thread end of the second bolt is by two set nut lockings, second U-shaped drag to buckle be connected with tow strap, the other end of described tow strap is connected with ball float.
Wherein, described first bolt is single ended bolt, or is stud bolt.
Wherein, described tow strap is the wire rope of diameter 5-~ 10mm.
Wherein, described first bolt and the second bolt are high-strength bolt.
The utility model compared with prior art has following beneficial effect: the utility model the thick screw nut such as to change into connecting pin and connects, and locked with double nut, and strength of joint is large, and traction cable can not be separated with sonar instrument, prevents sonar instrument from losing.And on the upside of sonar instrument afterbody, tie point installs a tow strap additional, length is greater than the degree of depth of work waters water, the other end of tow strap connects ball float, the buoyancy of ball float is greater than the weight of wire rope, so no matter after any waters sonar instrument is lost, all find target by floating thing or ball float, and utilize tow strap to salvage, huge economic loss can be retrieved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 use structural representation of the present utility model.
Fig. 3 is the first link in Fig. 1 and the first U-shaped mounting structure schematic diagram dragging button.

Embodiment
Be described in further detail the utility model by reference to the accompanying drawings now, accompanying drawing is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
As Figure 1-4, a kind of anti-lost instrument of sonar under water, comprise body 1, Sonar Signal generator is provided with in described body 1, the front end of described body 1 is provided with towing device 2, described towing device 2 comprises the first link 3 and first and U-shapedly drags button 4, first link 3 has the first through hole 5, first U-shaped dragging on the both sides connecting rod of button 4 openend all has the first mounting hole, described first through hole 5 is connected by installing the first bolt 6 with in two the first mounting holes, the thread end of the first bolt 6 is locked by two the first bolts 6, described first U-shaped dragging on button 4 is connected with traction cable 7.The rear end of body 1 is provided with loss prevention device 16, described loss prevention device 16 comprises the second link 8 and second and U-shapedly drags button 9, second link 8 has the second through hole 10, the second U-shaped both sides connecting rod dragging button 9 to drag button openend has the second mounting hole, described second through hole 10 is connected by installing the second bolt 11 with the second U-shaped dragging in button 9, the thread end of the second bolt 11 is locked by two set nuts 14, second U-shaped dragging on button 9 is connected with tow strap 12, the other end of tow strap 12 is connected with ball float 13, the buoyancy of ball float 13 is greater than the weight of tow strap 12, the length of tow strap 12 is greater than the depth of water in work waters, such ball float 13 is bubbled through the water column on 15 always, be convenient to observe and salvage.
Wherein, according to actual needs, the first bolt 6 can be single ended bolt, and only need to spin two set nuts 14 at thread end, the intensity of bolt is large, is not easy bending loss; Also can be stud bolt, two thread end of stud bolt all will spin set nut 14, and locked by two set nuts 14, the first bolt in the random vibration of radial direction, can not prevent loss.
