[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1 , 2As shown in Figure 3, a surveying instrument for engineering surveying and mapping comprises a leg 1; a surveying instrument body 11 is installed on the top of the leg 1; a fixing plate 12 is fixedly connected to the top of the surveying instrument body 11; two groups of slide grooves 13 are opened in the middle of the fixing plate 12; a first shielding plate 14 is connected to the outer wall of the fixing plate 12 with a torsion spring; two groups of pull ropes 15 are fixedly connected to the middle of the first shielding plate 14, and the pull ropes 15 are arranged to penetrate the middle of the slide groove 13; a slide plate 16 is fixedly connected to the end of the pull rope 15; the slide plate 16 is arranged to slide on the inner wall of the fixing plate 12; when working, the staff needs to unfold a plurality of legs 1 and support and fix the surveying instrument body 11, and then the staff can turn on the switch of the surveying instrument body 11 to map the terrain of the desert environment. By arranging the fixing plate 12 on the top of the surveying instrument body 11, when the surveying instrument body 11 is in use, the staff can place external heavy objects on the top of the slide plate 16, and under the action of the gravity of the heavy objects, the staff can put the heavy objects on the top of the slide plate 16. When the first shielding plate 14 is in use, the slide plate 16 will slide downward and pull the multiple pull ropes 15 while sliding, so that the pull ropes 15 move in the middle of the slide groove 13. Because the end of the pull rope 15 is in contact with the middle of the first shielding plate 14, the two groups of first shielding plates 14 will be simultaneously unfolded under the action of the pulling force, and the surveying instrument body 11 will be blocked as a whole at the bottom of the first shielding plate 14. When the first shielding plate 14 needs to be stored, the weight on the top of the slide plate 16 can be removed, and the slide plate 16 can be pulled upward again with the help of the torque of the first shielding plate 14 returning to its original position. This step, together with the two groups of first shielding plates 14 that are unfolded, can reduce the problem of low accuracy of the surveying instrument body 11 when testing the desert environment after the surveying instrument body 11 is used for a long time in a high temperature and sunshine environment. Under the action of the weight on the top of the slide plate 16, the stability of the surveying instrument body 11 during use can be improved, and the problem of the overall leg 1 being tilted or even tipped over by the external wind can be reduced.
[0025] like Figure 2 and 4As shown, two groups of second shielding plates 2 are fixedly connected to the top of the fixed plate 12; a connecting rod 21 is fixedly connected to the middle of the second shielding plate 2; a groove 22 is opened at the end of the connecting rod 21; two groups of first springs 23 are fixedly connected to the inner wall of the groove 22; a sliding rod 24 is fixedly connected to the end of the first spring 23, and the sliding rod 24 is slidably arranged in the middle of the connecting rod 21; a bell 25 is fixedly connected to the end of the sliding rod 24; when working, by arranging the second shielding plate 2 on the top of the first shielding plate 14, the first shielding plate 14 will synchronously drive the second shielding plate 2 to rotate while rotating. Because a connecting rod 21 is arranged in the middle of the second shielding plate 2, the connecting rod 21 will change from horizontal to vertical at this time, and block the heavy objects placed on the top of the slide plate 16, When the heavy object on the top of the slide plate 16 is offset at an angle and approaches the middle of the connecting rod 21 during use, it will first contact the sliding rod 24 protruding from the middle of the connecting rod 21 and squeeze the sliding rod 24, so that the middle of the first spring 23 is stretched. When the sliding rod 24 moves, under the action of inertia, the two groups of bells 25 can swing in sequence and make sounds to warn the staff. This step, combined with the second baffle plate 2, can further increase the shading area of the top of the surveying instrument body 11, and the vertical connecting rod 21 can reduce the problem of the heavy object on the top of the slide plate 16 slipping off. Combined with the bell 25, the working position deviation of the heavy object on the top of the slide plate 16 can be reduced, resulting in the problem of the overall center of gravity of the leg 1 being unstable and difficult to detect.
[0026] like Figure 4 As shown, a reinforcement rod 3 is fixedly connected to the middle of the slide bar 24; two groups of second springs 31 are fixedly connected to the middle of the reinforcement rod 3; a ball 32 is fixedly connected to the end of the second spring 31, and the ball 32 is arranged close to the middle of the first spring 23; during operation, by arranging a reinforcement rod 3 in the middle of the slide bar 24, the weight can drive another group of bells 25 to shake under the action of the reinforcement rod 3 while pushing one group of slide bars 24, and when the reinforcement rod 3 is moving, the two groups of second springs 31 will shake synchronously, and the ball 32 will hit the middle of the bell 25. This step, combined with the reinforcement rod 3 arranged at the end of the slide bar 24, can improve the synchronization of the two groups of bells 25 when working, and improve the sound of the bell 25. The frequently shaking ball 32 can increase the frequency of the sound of the bell 25, further improving the staff's awareness of the problem of displacement of the working position of the heavy object.
[0027] like Figure 2 and 5As shown, the bottom of the first shielding plate 14 is hinged with a rotating plate 4; two groups of third springs 41 are fixedly connected to the top of the rotating plate 4, and the other end of the third spring 41 is fixedly connected to the bottom wall of the slide plate 16; when working, by arranging a rotating plate 4 at the bottom of the slide plate 16, when the slide plate 16 is in a suspended state, under the action of the elastic force of the two groups of third springs 41, the rotating plate 4 will be in an inclined state, and when the slide plate 16 is rapidly lowered, the inclined surface can be used to blow and clean the dust particles attached to the bottom wall of the fixed plate 12 in one direction, and after the end of the rotating plate 4 contacts the bottom wall of the fixed plate 12, the rotating plate 4 can be stored as a whole to the bottom of the slide plate 16 with the help of pressure. This step cooperates with the setting of the rotating plate 4 to improve the cleanliness of the bottom wall of the fixed plate 12 and reduce the number of dust particles attached to the bottom wall of the fixed plate 12, which causes the sliding plate 16 to shake during the process of placing the top of the fixed plate 12.
[0028] like Figure 4 As shown, the end of the bell 25 is fixedly connected to a frame 5; the middle part of the frame 5 is arranged in an arc shape; the inner wall of the frame 5 is fixedly connected to a filter 51; when working, by arranging a third spring 41 at the end of the bell 25, some external dust particles will be blocked by the filter 51, and the curved frame 5 is used to deal with the attached dust particles. This step cooperates with the filter 51 to reduce the problem that some dust particles enter the interior of the bell 25, resulting in a smaller sound of the bell 25, thereby increasing the service life of the bell 25, and the curved frame 5 can reduce the length of time that dust particles are attached to the middle part of the filter 51.
[0029] like Figure 3 As shown, two groups of rubber plates 6 are fixedly connected to the inner wall of the slide groove 13, and the two groups of rubber plates 6 are symmetrically arranged; the end of the rubber plate 6 is arranged in contact with the middle of the pull rope 15; when working, by arranging two groups of rubber plates 6 on the inner wall of the slide groove 13, when the pull rope 15 is pulled to move, the two groups of rubber plates 6 will contact the pull rope 15. This step cooperates with the two groups of rubber plates 6 made of soft materials to reduce the adhesion of some impurities in the middle of the pull rope 15, and at the same time can reduce the problem of large wear caused by the pull rope 15 directly contacting the inner wall of the slide groove 13.
[0030] like Figure 4 As shown, the end of the slide bar 24 is fixedly connected to a limiting member 7; the limiting member 7 is arranged close to one side of the fixed plate 12; when working, by arranging the limiting member 7 at the end of the slide bar 24, the heavy object will contact the limiting member 7 before approaching the slide bar 24. This step cooperates with the limiting member 7 to increase the friction force of the heavy object squeezing the slide bar 24, and at the same time, the sliding trajectory of the slide bar 24 can be limited, thereby reducing the problem of the slide bar 24 retracting to the inner wall of the connecting rod 21 and causing difficulty in taking it out.
[0031] The working principle is that the multiple legs 1 are unfolded and the surveying instrument body 11 is supported and fixed, and then the staff can turn on the surveying instrument body 11 to survey the terrain of the desert environment. By setting a fixing plate 12 on the top of the surveying instrument body 11, when the surveying instrument body 11 is in use, the staff can place external heavy objects on the top of the slide plate 16, and under the action of the gravity of the heavy objects, the slide plate 16 will slide downward, and pull multiple pull ropes 15 while sliding, so that the pull ropes 15 move in the middle of the slide groove 13. Because the ends of the pull ropes 15 are in contact with the middle of the first shielding plate 14, the two groups of first shielding plates 14 will be synchronously unfolded under the action of the pulling force, and the whole surveying instrument body 11 The first shielding plate 14 is provided with a second shielding plate 2 on the top of the first shielding plate 14, so that the first shielding plate 14 can rotate while driving the second shielding plate 2 to rotate synchronously. Because a connecting rod 21 is provided in the middle of the second shielding plate 2, the connecting rod 21 will change from horizontal to vertical at this time, and block the heavy object placed on the top of the slide plate 16. When the heavy object on the top of the slide plate 16 is offset at an angle during use and approaches the middle of the connecting rod 21, it will move before the sliding rod 2 protruding from the middle of the connecting rod 21. 4 contacts and squeezes the slide bar 24, so that the middle part of the first spring 23 is stretched, and when the slide bar 24 is moving, under the action of inertia, the two groups of bells 25 can shake in sequence and produce sounds to warn the staff, and a reinforcing rod 3 is provided in the middle of the slide bar 24, so that when the heavy object pushes one group of slide bars 24, the other group of bells 25 can be driven to shake under the action of the reinforcing rod 3, and when the reinforcing rod 3 is moving, the two groups of second springs 31 will shake synchronously, and the ball 32 will hit the middle part of the bell 25, and by providing a rotating plate 4 at the bottom of the slide plate 16, when the slide plate 16 is in a suspended state, under the action of the elastic force of the two groups of third springs 41, the rotating plate 4 will be in an inclined state, and When the slide plate 16 descends rapidly, the inclined surface can be used to blow and clean the dust particles attached to the bottom wall of the fixed plate 12 in one direction. After the end of the rotating plate 4 contacts the bottom wall of the fixed plate 12, the rotating plate 4 can be stored as a whole at the bottom of the slide plate 16 with the help of pressure. By providing a third spring 41 at the end of the bell 25, some external dust particles will be blocked by the filter 51, and the attached dust particles will be disposed of by the curved frame 5. By providing two groups of rubber plates 6 on the inner wall of the slide groove 13, when the pull rope 15 is pulled to move, the two groups of rubber plates 6 will contact the pull rope 15. By providing a limiting member 7 at the end of the slide bar 24, the heavy object will contact the limiting member 7 before approaching the slide bar 24.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
