In detail, the distribution device 51 may be provided with a switching mode power supply (SMPS) or the like. The power supplied from the DC power source 53, such as a battery built in the power supply control unit 50, It is possible to convert the current to have the current / voltage suitable for the driving of the units 40a and 40b and distribute them to the respective coil portions 42a and 42b.

As a result, a separate rectifying device such as an inverter is not required, so that a more compact product can be provided.

At this time, the required current / voltage at the time of driving the magnetic core portions 40a and 40b may be set to correspond to the weight of the slide body portion 20 and the supports 20a and 20b or the size of the clearance space.

The switching elements 52a and 52b are provided in pairs so that they are provided in the distribution lines 51a and 51b between the coil parts 42a and 42b of the magnetic core parts 40a and 40b and the distribution device 51. [ .

The support portions 20a and 20b are formed such that when the slide body 20 reciprocates, the ends of the support portions 20a and 20b are struck by the magnetic core portions 40a and 40b and the base cores 30a and 30b, k extending from one end and the other end thereof.

The first base core portion 30a is fixed to the slide body portion 20 so that the first base core portion 30a and the slide body portion 20 are engaged with each other at one end .

As the first base core portion 30a strikes the first magnetic core portion 40a, the slide body portion 20 and the support portions 20a and 20b, the first base core 30a, Impact energy corresponding to the weight of the base core 30b is generated.

Also, when power is applied to the first coil part 42a and power is applied to the second coil part 42b, the slide body part 20 is moved in the opposite direction and the same impact energy can be generated.

At this time, the generated impact energy is transmitted to the target conduit (1), and the sludge corresponding to the inner wall surface of the target conduit (1) can be removed.

Furthermore, as the slide body 20 reciprocates in a predetermined period, periodic vibration shocks can be continuously applied to the object pipeline 1, so that adhesion of the sludge counterpart to the inner wall surface of the object pipeline 1 can be prevented Can be blocked.

As a result, the transfer efficiency of the fluid or the minute sludge using the object pipeline 1 can be improved.

The impact energy according to the speed and weight of the slide body 20 can be maximized at the same power.

Accordingly, the removal efficiency of the sludge counterpart to the inner wall surface of the object channel 1 can be improved.

Since the base core portions 30a and 30b are pulled in both directions between the pair of spaced magnetic core portions 40a and 40b and the slide body portion 20 can be reciprocated, A separate member such as a bolt or a spring for separating the core portion and the magnetic core portion is not required and the abnormal vibration and the drop of the impact amount due to the unbalanced wear of the bolt and the spring and the elasticity of the spring can be prevented.

The frictional force is reduced when the slide body 20 is moved through the bearing 11 so that the inertial impact due to the weight of the slide body 20 can be increased. Wear of the component parts such as the support parts 20, 20a and 20b is minimized, so that the durability of the product can be improved.

The support portions 20a and 20b may be formed to prevent the support portions 20a and 20b from being separated from the space between the magnetic core portions 40a and 40b and the housing 10 when the slide body 20 is reciprocated. May be formed to have a length exceeding the sum of the maximum spacing distance between the magnetic core portions 40a and 40b and the base core portions 30a and 30b and the total length of the base core portions 30a and 30b.

That is, the length a of the first support portion 120a is greater than the length b of the first magnetic core portion 40a and the length c of the first base core portion 30a The length of the second supporting portion 120b may be greater than the length of the second magnetic core portion 40b and the length of the second base core portion 30b.

More specifically, when power is applied to the first coil portion 42a, magnetic attraction is generated in the first magnetic core portion 40a, and the base core portion 30a is pulled toward one end of the guide space k.

Since the first base core portion 30a is fixed to the slide body portion 20, the first base core portion 30a and the slide body portion 20 together form a single end .

One end of the first support part 120a strikes the inner surface of the cover member 60 exposed to the outside of the first magnetic core part 40a and the slide body part 20 and the support parts 120a and 120b, , The first base core 30a, and the second base core 30b.

At this time, due to the length (a) of the first supporting part 120a, one end of the first supporting part 120a is in contact with the inner surface of the cover member 60 exposed to the outside of the first magnetic core part 40a The first base core portion 30a and the first magnetic core portion 40a may be spaced apart from each other.

Also, when power is applied to the first coil part 42a and power is applied to the second coil part 42b, the slide body part 20 is moved in the opposite direction and the same impact energy can be generated.

At this time, the other end of the second support portion 120b is collided with the inner surface of the other end of the housing 10 exposed to the outside of the second magnetic core portion 40b due to the length of the second support portion 120b The second base core portion 30b and the second magnetic core portion 40b may be spaced apart from each other.

Accordingly, the portion where the direct vibration impact is generated and the portion where the magnetic attraction is generated for generating the vibration impact can be separated, and the magnetic core portions 40a, 40b to the base core portions 30a, 30b can be minimized and the durability of the product can be improved.

As described above, the present invention is not limited to the above-described embodiments, and variations and modifications may be made by those skilled in the art without departing from the scope of the present invention. And such modifications are within the scope of the present invention.
