る方法が公知となっている。2. Description of the Related Art When a fluid is sent through a pipe, various kinds of deposits are generated in the pipe according to the purpose of use. Therefore, the deposits affect the fluid, and the deposits gradually accumulate and hinder the flow. For this reason, pigs are generally used in many cases to remove deposits in the pipe. In addition, in order to check for abnormal spots in the piping or to check the status of the scale, insert a camera cable with a camera head equipped with an illumination light and lens at the tip into the pipe together with the camera head, and take an image with this camera. There is known a method of projecting and monitoring the image on a monitor provided on the ground.

る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a pipe monitoring pig of the present invention will be described with reference to the drawings. 1 and 2 show a pig 1 formed of a foamed synthetic resin material having elasticity.
A main body 3 having an outer periphery adapted to the inner diameter of the main body, a battery 4 serving as a power supply and a radio device 5 are built in a hollow portion inside the main body 3, and furthermore, the main body 3 can be swung toward the center on the front side. A plurality of lights 7 are arranged around the CCD camera 6 and the CCD camera 6 in the center. The pig 1 is moved by an appropriate means such as a propulsion movement using the pressure of a fluid in the pipe 2 or a pulling of a connecting yarn connected to the pig 1 to inspect the inner wall surface of the pipe 2. FIG. 3 shows a surveillance system, in which a pig 1 propelled by means of fluid or traction in the tube 2 is transmitted by radio and a signal is taken by radio. The captured image can be monitored by a TV monitor 10 from a wireless device 9 connected to a power supply 8 provided outside by a wireless device 5.

されるので安定する等の特徴がある。As described above, according to the present invention, the pig for propelling the inside of the pipe is used for inspecting the inside of the pipe or for examining the situation inside the pig using a CCD camera and lighting by a wireless action of a wireless device (power unit) using a battery as a power source. Since the image is clearly displayed and can be monitored with an external TV monitor, the inside of the tube can be grasped at a glance, which is convenient. Further, the CCD camera can be remotely controlled by wireless means in the pig and does not use a conventional camera cable, so that the operation is not troublesome and troublesome. Further, the CCD camera has a feature that it is stabilized because it is housed in a pig.
