Description

Technical Field

[0001] The utility model relates to the field of helicopter aeromagnetic measurement, in particular to an aeromagnetic probe mounting device suitable for a helicopter. Background Art

[0002] At present, helicopter aeromagnetic surveying is an important method of airborne geophysical exploration and plays an irreplaceable role to this day. Helicopter aeromagnetic generally involves integrating the aeromagnetic instrument system onto an aircraft through modification, forming a helicopter aeromagnetic system for flight measurement operations. The installation of the aeromagnetic probe is an important part of the system modification. Generally, the aeromagnetic probe is directly fixed to the center of the lower belly of the aircraft, or installed and fixed to the helicopter skid on one side of the lower belly. The front end of the probe is aligned with the flight direction of the helicopter. The probe is installed separately without a support rod. In this case, during actual flight measurement operations, the probe will not only generate high-frequency vibrations, but also produce large swings up and down or left and right, which will have a significant impact on the aeromagnetic measurement results.

[0003] According to the published patent 202121036473.9, an aeromagnetic probe mounting device suitable for helicopters includes a detachable three-section probe, the rear of the probe is connected to one side of a skid, the skid is installed on the belly of the helicopter, and the front end of the skid on the same side is connected to the front of the probe through a vertical support rod, the vertical support rod is connected to the probe through a vertical connecting rod, the other side of the skid is connected to the front of the probe through an inclined support rod, the inclined support rod is connected to the probe through an inclined connecting rod, and the vertical support rod and the inclined support rod are connected by a cross bar. The present invention ensures the stability of the probe rod during aerial geophysical prospecting, aeromagnetic or flight measurement operations involving multiple parameters of aeromagnetic, and at the same time, the aeromagnetic probe rod will not generate interfering eddy current fields during flight measurement operations, and is more convenient to transport after disassembly. In the process of realizing the present invention, the inventors found that at least the following problems exist in the prior art and have not been solved. Although the support rods of the aeromagnetic probe rod, the probe rod and the support rods, and the support rods are all connected and fixed, and the probe rod is a detachable three-section design, compared with general aeromagnetic probe rods, the stability after installation is better, no interfering eddy current fields will be generated during flight measurement operations, and is more convenient to transport after disassembly, and the problem of large swing of the aeromagnetic probe rod during aerial geophysical prospecting, aeromagnetic or flight measurement operations involving multiple parameters of aeromagnetic is solved, during use, the traditional aeromagnetic probe rod mounting device suitable for helicopters still needs to fix the probe rod on the top side of the sled, resulting in the probe rod occupying the external space of the sled, affecting the use of the sled. At the same time, multiple support rods are connected to each other, and the support rods will form a frame shape, resulting in increased wind resistance and increased energy consumption of the helicopter. Therefore, it is necessary to design a new technical solution. Utility Model Content

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, adapt to actual needs, and provide an aeromagnetic probe rod mounting device suitable for helicopters, so as to solve the technical problem that the current traditional aeromagnetic probe rod mounting device suitable for helicopters also requires the probe rod to be fixed on the top side of the skid, resulting in the probe rod occupying the external space of the skid, affecting the use of the skid, and at the same time, multiple support rods are connected to each other, and the support rods will form a frame shape, resulting in greater wind resistance and increased energy consumption of the helicopter.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is to design an aeromagnetic probe mounting device suitable for a helicopter, including two skid bodies and also including:

[0006] Two first supporting strips are respectively fixed in the middle between the two skid bodies;

[0007] An aeromagnetic probe rod mounting mechanism is fixed between the two first support strips, and the aeromagnetic probe rod mounting mechanism includes a fixing ring, a first fixing cylinder is fixed to both the front and rear ends of the fixing ring, a second fixing cylinder is passed through one end of the first fixing cylinder, a damping block is fixed to one end of the second fixing cylinder located inside the first fixing cylinder, a spring is fixed to one end of the damping block away from the second fixing cylinder, and the first fixing cylinder is fixed to one end of the spring away from the damping block;

[0008] A semicircular clamping block is installed on one end of the second fixing tube away from the first fixing tube.

[0009] Preferably, the two semicircular clamping blocks clamp a probe rod therein.

[0010] Preferably, second support strips are fixed at both upper and lower ends of both sides between the two skid bodies, and fixing bolts pass through the interior of the second support strips.

[0011] Preferably, thread grooves are provided on both sides of the upper and lower ends of the probe rod, and fixing bolts are threadedly connected inside the thread grooves.

[0012] Preferably, a groove is formed at one end of the fixing bolt, and a wireless pressure sensor is installed inside the groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model utilizes the elastic force of the spring in the first fixed tube to drive the damping block and the second fixed tube to move through the second fixed tube to drive the semicircular clamping block pair to move, thereby limiting and clamping probe rods of different sizes. Moreover, since the probe rod passes directly through the middle position of the sled body, it does not occupy the space outside the sled body and will not affect the normal use of the sled body. At the same time, it avoids the setting of a frame-shaped support rod, reduces the wind resistance caused by the frame-shaped connection structure, and solves the problem that the traditional aeromagnetic probe rod mounting device suitable for helicopters also needs to fix the probe rod on the top side of the sled, resulting in the probe rod occupying the external space of the sled and affecting the use of the sled. At the same time, multiple support rods are connected to each other, and the support rods will form a frame shape, which will increase the wind resistance and increase the energy consumption of the helicopter.

[0015] 2. The utility model combines the second support strip, the fixing bolt and the threaded groove, so that after the probe rod passes through the fixing ring and is clamped and limited, multiple fixing bolts are threadedly connected to the threaded grooves at the upper and lower positions of the probe rod, thereby realizing triple limit fixation of the two ends and the middle position of the probe rod. Moreover, a wireless pressure sensor is provided inside the fixing bolt, which can detect the pressure of the fixing bolt in real time after the fixing bolt is threadedly connected to the threaded groove. When the pressure of the fixing bolt changes, it indicates that the fixing bolt is loose, and the staff can deal with it in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: An aeromagnetic probe mounting device suitable for helicopters, see Figures 1 to 3, including two skid bodies 1, and also including: two first support strips 2, respectively fixed in the middle between the two skid bodies 1; an aeromagnetic probe rod 302 mounting mechanism, fixed between the two first support strips 2, the aeromagnetic probe rod 302 mounting mechanism includes a fixing ring 201, the front and rear ends of the fixing ring 201 are fixed with a first fixing cylinder 202, one end of the first fixing cylinder 202 is penetrated by a second fixing cylinder 205, and the end of the second fixing cylinder 205 located in the first fixing cylinder 202 is fixed with a damping block 204, and the end of the damping block 204 away from the second fixing cylinder 205 is fixed with a spring 203, and the end of the spring 203 away from the damping block 204 is fixed with the first fixing cylinder 202; a semicircular clamping block 206 is installed at one end of the second fixing cylinder 205 away from the first fixing cylinder 202. First, the probe rod 302 passes through the fixing ring 201 from the middle between the two skid bodies 1. Since the inner wall of the fixing ring 201 is provided with a first fixing The fixed cylinder 202 can utilize the elastic force of the spring 203 in the first fixed cylinder 202 to drive the damping block 204 and the second fixed cylinder 205 to move, and drive the semicircular clamping block 206 to move through the second fixed cylinder 205, so as to limit and clamp the probe rods 302 of different sizes. Moreover, since the probe rod 302 passes directly through the middle position of the skid body 1, it does not occupy the space outside the skid body 1 and will not affect the normal use of the skid body 1. At the same time, it avoids the need to set a frame-shaped support rod, reduces the wind resistance caused by the frame-shaped connection structure, and solves the problem that the traditional aeromagnetic probe rod 302 mounting device suitable for helicopters also needs to fix the probe rod 302 on the top side of the skid, resulting in the probe rod 302 occupying the external space of the skid, affecting the use of the skid. At the same time, when multiple support rods are connected to each other, the support rods will form a frame shape, resulting in increased wind resistance and increased energy consumption of the helicopter.

[0022] For details, see Figure 1 The two semicircular clamping blocks 206 clamp the probe rod 302 therein.

[0023] For further information, see Figure 1 Second support strips 3 are fixed at both upper and lower ends of the two sides between the two skid bodies 1 , and fixing bolts 301 pass through the interior of the second support strips 3 .

[0024] It is worth noting that, see Figure 1 , thread grooves 303 are provided on both sides of the upper and lower ends of the probe rod 302, and the internal threads of the thread grooves 303 are connected with fixing bolts 301. After the probe rod 302 passes through the fixing ring 201 and is clamped and limited, multiple fixing bolts 301 can pass through the second support strip 3 and be threadedly connected to the thread grooves 303 at the upper and lower positions of the probe rod 302, and cooperate with the semicircular clamping block 206, thereby realizing triple limit fixation of the two ends and the middle position of the probe rod 302.

[0025] It is worth noting that see Figure 3 A groove 304 is provided at one end of the fixing bolt 301, and a wireless pressure sensor 305 is installed inside the groove 304. A wireless pressure sensor 305 is provided inside the fixing bolt 301. After the fixing bolt 301 is threadedly connected to the thread groove 303, the pressure of the fixing bolt 301 can be detected in real time. When the pressure of the fixing bolt 301 changes, it means that the fixing bolt 301 is loose, and the staff can deal with it in time.

[0026] When using an aeromagnetic probe rod mounting device suitable for a helicopter, the probe rod 302 is first passed through the fixing ring 201 from the middle between the two skid bodies 1. Since the first fixing cylinder 202 is provided on the inner wall of the fixing ring 201, the elastic force of the spring 203 in the first fixing cylinder 202 can be used to drive the damping block 204 and the second fixing cylinder 205 to move, and the semicircular clamping block 206 is driven to move through the second fixing cylinder 205, so as to limit and clamp probe rods 302 of different sizes. Moreover, since the probe rod 302 is passed directly through the middle position of the skid body 1, it does not occupy the space outside the skid body 1 and will not affect the normal use of the skid body 1. At the same time, the setting of a frame-shaped support rod is avoided. The wind resistance caused by the frame-shaped connection structure is reduced. After the probe rod 302 passes through the fixing ring 201 and is clamped and limited, multiple fixing bolts 301 can pass through the second support strip 3 and be threadedly connected to the thread grooves 303 at the upper and lower positions of the probe rod 302, and cooperate with the semicircular clamping block 206, thereby realizing triple limit fixation of the two ends and the middle position of the probe rod 302. A wireless pressure sensor 305 is provided inside the fixing bolt 301. After the fixing bolt 301 is threadedly connected to the thread groove 303, the pressure of the fixing bolt 301 can be detected in real time. When the pressure of the fixing bolt 301 changes, it indicates that the fixing bolt 301 is loose, and the staff can deal with it in time.
