The test methods adopted by such national military standards mostly use ground artillery as the test platform, assemble the electronic detonation module on the applicable projectile, and evaluate the detection capability of the electronic detonation module by real-life shooting to replicate the action state of the electronic detonation module in the actual combat environment. This test method truly realizes the terminal ballistic characteristics of the product, but its non-destructive recovery rate is extremely low, especially in the information-based interference environment and the multi-background environment. The anti-interference ability of the electronic detonation module is difficult to obtain through ammunition shooting tests. Summary of the invention

In the process of sliding from the highest point to the corresponding position of the fixed point of the lower end of the elastic rope on the steel cable, the elastic rope provides the pulley with a driving force to slide downward along the steel cable. This power and the component of the pulley's gravity along the steel cable downward drive the pulley to accelerate together to meet the speed requirement of the projectile during the test; when the pulley passes the corresponding position, the elastic rope provides the pulley with a damping force along the steel cable upward to assist in intercepting the pulley; a blocking cable mechanism is provided at the lower end of the steel cable to stop the pulley; ground effect objects required for the test are provided on the ground below the steel cable, and data acquisition equipment is arranged on the ground.

[0006] Furthermore, multiple ground fixing points are arranged in a direction away from the test tower.

[0007] Furthermore, a first cement base is fixed on the ground below the steel cable, a tension measurement system is arranged in the first cement base, and a protective steel plate is arranged above the tension measurement system; a rope connecting hook is arranged at the lower end of the elastic rope, the rope connecting hook passes through the protective steel plate and is connected to the tension measurement system, and the tension system is installed on a transfer steel plate fixed to the first cement base.

[0008] Furthermore, the blocking cable mechanism includes an intercepting rope, which is arranged on one side of the ground fixed point at the lower end of the steel cable, located above the steel cable and perpendicular to the steel cable; dampers and fixed steel plates are respectively provided at both ends of the intercepting rope, and the fixed steel plates are respectively fixed on the second cement base.

[0009] Furthermore, the pulley includes an intermediate connecting plate, and two sets of pulleys are installed on the upper surface of the intermediate connecting plate. The steel cable passes through each set of pulleys to install the pulley on the steel cable; an adapter plate is set on the lower surface of the intermediate connecting plate, and an adjustment groove and a bolt hole are opened on the adapter plate.

DETAILED DESCRIPTION

[0027] See attached Figure 1 The present invention provides a low-speed proximity electronic detonation module sliding rope driving and intercepting device, comprising a test tower 12 and a steel cable 4, one end of the steel cable 4 is fixed to the top of the test tower 12, and the other end of the steel cable 4 is fixed to a ground fixing point 11; a plurality of ground fixing points 11 are arranged in a direction away from the test tower 12, and the steel cable 4 is connected to different ground fixing points 11, so that the steel cable 4 and the ground are at different angles, so as to cooperate with the pulley 3 to simulate the terminal trajectory of the projectile; a pulley 3 for simulating the projectile is installed on the steel cable 4, and a proximity electronic detonation module 13 with an adjustable installation angle is carried on the pulley 3, and the angle of the proximity electronic detonation module 13 relative to the pulley 3 is adjusted to simulate different attack angles of the projectile; an elastic rope 5 is arranged below the steel cable 4, and the elastic rope 5 is connected to the pulley 3; the pulley During the whole process of sliding on the steel cable 4, the elastic rope 5 is in a stretched state; during the process of the pulley 3 sliding from the highest point of the steel cable 4 to the corresponding position A of the lower end fixing point of the elastic rope 5 on the steel cable 4, the elastic rope 5 provides the pulley 3 with a driving force to slide downward along the steel cable 4, and the driving force and the downward component of the weight of the pulley 3 along the steel cable 4 jointly drive the pulley 3 to accelerate, so as to meet the speed requirement of the projectile during the test; after the pulley 3 passes the corresponding position A, the elastic rope 5 provides the pulley 3 with a damping force in the upward direction along the steel cable 4 to assist in intercepting the pulley 3; a blocking rope mechanism is arranged at the lower end of the steel cable 4, which is used to intercept the pulley 3, so as to realize the non-destructive recovery of the near-explosion electronic detonation module 13, and facilitate repeated tests; ground effect objects required for the test are arranged on the ground below the steel cable 4, and data acquisition equipment is arranged on the ground.

[0028] In this solution, the proximity electronic detonation module 13 is installed on the pulley 3 to simulate the projectile, and the pulley 3 slides on the steel cable 4 to simulate the terminal trajectory; the installation angle of the proximity electronic detonation module 13 is adjusted to simulate different attack angles of the projectile, and different ground effect objects are set on the ground according to the test requirements, and data acquisition equipment is arranged, so that different tests can be simulated and corresponding data can be collected.

[0029] Considering that it is difficult to reach the required speed at the end point of the trajectory only by gravity descent of the pulley 3, and if the steel cable 4 is lengthened and the test tower 12 is raised, the cost will be greatly increased, so the present invention sets an elastic rope 5 on the ground below the steel cable 4.

[0030] A first cement base 6 is fixed on the ground below the steel cable 4, a tension measurement system 7 is arranged in the first cement base 6, and a protective steel plate 17 is arranged above the tension measurement system 7; a rope connection hook is arranged at the lower end of the elastic rope 5, and the rope connection hook passes through the protective steel plate 17 and is connected to the tension measurement system 7, and the tension system is installed on a transfer steel plate 18 fixed to the first cement base 6. The tension measurement system 7 can monitor the tension change of the elastic rope 5 during the test, thereby providing data support for the test.

[0031] The elastic rope 5 in this solution is in a stretched state during the entire movement of the pulley 3; see Figure 1 , let the corresponding position of the lower end fixing point of the elastic rope 5 (i.e. the place where the elastic rope 5 is connected to the tension measurement system 7 through the rope connecting hook) on the steel cable 4 be A, and A is the intersection of the vertical line passing through the lower end fixing point of the elastic rope 5 and the steel cable 4; then in the process of the pulley 3 sliding from the starting point above the steel cable 4 to point A, the force exerted by the elastic rope 5 on the pulley 3 will always produce a component downward along the steel cable 4, and this component together with the component of the pulley 3's own weight downward along the steel cable 4 jointly drives the pulley 3 to accelerate, thereby The pulley 3 is enabled to reach the speed required by the test at the end of the steel cable 4; by selecting elastic ropes 5 with different elastic coefficients, or pre-fabricating different elastic stretching amounts, the magnitude of the downward component of the force of the elastic rope 5 on the pulley 3 along the steel cable 4 can be adjusted, thereby adjusting the speed of the pulley 3 on the steel cable 4; and when the pulley 3 passes through point A on the steel cable 4, the force of the elastic rope 5 on the pulley 3 will always produce an upward component along the steel cable 4, and this part is used as the damping force of the pulley 3 to intercept the pulley 3.

[0032] In order to better achieve lossless recovery, this solution sets up an arresting cable mechanism; see Attachment Figure 1 The blocking cable mechanism includes an intercepting rope 8, which is arranged on one side of a ground fixed point 11 at the lower end of the steel cable 4, above the steel cable 4 and perpendicular to the steel cable 4, about 2m above the ground; dampers 9 and fixed steel plates are respectively arranged at both ends of the intercepting rope 8, and the fixed steel plates are respectively fixed on the second cement base 10.

[0033] When the pulley 3 contacts the intercepting rope 8, the pulley 3 is decelerated continuously under the action of the damper 9 and finally stops moving. At this time, the proximity electronic detonation module 13 can be recovered.

[0034] See attached Figure 2 The pulley 3 includes an intermediate connecting plate 16, and two groups of pulleys 15 are installed on the upper surface of the intermediate connecting plate 16. The steel cable 4 passes through each group of pulleys 15 to install the pulley 3 on the steel cable 4; an adapter plate 14 is set on the lower surface of the intermediate connecting plate 16, and an adjustment groove and a bolt hole are provided on the adapter plate 14. The proximity electronic detonation module 13 cooperates with different bolt holes and adjustment grooves to adjust its installation angle.

[0035] See attached Figure 1 and Figure 2 In order to facilitate the resetting and testing of the pulley 3, the present invention installs a winch 1 on the top of the test tower 12, and a trailer 2 connected to the winch 1 is arranged on the steel cable 4, and the trailer 2 is connected to the pulley 3 through a release mechanism; the trailer 2 is driven by the winch 1 to drive the pulley 3 to be reset for the next test; the release mechanism may be, for example, an electronic buckle, etc.

[0036] On the basis of the above technical solution, the present invention further provides a test method for a low-speed proximity electronic detonation module 13, the steps of which are as follows:

[0037] Step 1. Before the test, design the installation angle of the steel cable 4 and calculate the tension value of the elastic rope 5 according to the test technical requirements, so that the speed of the pulley 3 when sliding on the steel cable 4 to the action height of the proximity electronic detonation module 13 can meet the test requirements; in this example, the steel cable 4 is inclined at an angle of 45° (based on the measurement data at the end of the steel cable 4).

[0038] Step 2, setting corresponding ground effect objects according to the ground environment required for the proximity electronic detonation module 13 test.

[0039] For example, when evaluating the effect of the proximity electronic detonation module 13 on ordinary cultivated land, the soil used for cultivated land can be used to cover the ground; when evaluating the effect of the proximity electronic detonation module 13 on sandy and gravel land, sand and gravel can be laid on the ground; when evaluating the effect on the water surface, a corresponding pool can be made on the ground, etc.

[0040] Step 3, install the proximity electronic detonation module 13 on the pulley 3 and adjust the installation angle according to the test requirements to simulate the attack angle required for the test, then connect the elastic rope 5 to the pulley 3, and use the winch 1 and trailer 2 to drive the pulley 3 to the initial position above the steel cable 4.

[0041] Step 4, after arranging the data acquisition equipment on the ground, start the test; the data acquisition equipment is, for example, a signal acquisition instrument, a photoelectric conversion device, a speed meter, a high-speed camera, etc.;

[0042] The control release mechanism is opened, and the pulley 3 accelerates down along the steel cable 4 under the dual effects of its own gravity and the elastic rope 5. When the pulley 3 reaches the action height of the proximity electronic detonation module 13, the proximity electronic detonation module 13 generates an action signal and outputs it to the signal acquisition instrument or the photoelectric conversion device; when the pulley 3 reaches the end of the steel cable 4, it contacts the blocking cable mechanism and decelerates to 0m / s, thereby completing a test.

[0043] By repeating this step, the proximity electronic detonation module 13 can be repeatedly tested and tested. Meanwhile, a high-speed camera can be used to shoot the test process during the test to obtain relevant test data.

[0044] According to the various data collected during the above test process, the comprehensive effect of the proximity electronic detonation module 13 on different action surfaces at different falling speeds and different attack angles can be evaluated, and a basis can be provided for the later improvement and modification of the proximity electronic detonation module 13.
