In hydraulic engineering, in order to keep water paths such as rivers, ditches and ponds smooth and ensure water quality, electric sand pumping or sludge pumping is adopted to pump bottom sludge, river sand and the like, and the method is a common work. In order to extract sludge or silt deposited in offshore places such as rivers, ditches and ponds, the sand or silt extracting equipment needs to be fixed in the offshore places such as the rivers, ditches and ponds in a ship-borne mode (namely, areas with relatively slow water flow speed, large amounts of water bottom silt and river sand, corresponding small amounts of water bottom silt and river sand in areas with high water flow speed, and generally low probability of sand extraction and desilting).
In order to ensure that water flow does not impact the ship body to a non-operation area, fixing ropes need to be installed at two side ends of the ship body, and then the two fixing ropes are respectively fixed on fixed objects (such as trees) at two sides of a shore. Because the land shapes of both sides of the operation area are different, and not all the both sides of the shore of the operation area are provided with the fixed objects such as trees, when the both sides of the operation area are not provided with the proper fixed objects, the positioning of the ship in the operation area is influenced (if the soil of the both sides is soft, the both sides are not suitable for inserting articles such as fixed rods to fix the ship, and the positioning of the ship in the operation area is also influenced).

As shown in fig. 1, 2, 3 and 4, before the present invention is applied, the hull 8 is set in the working area by dragging with other ships, and then the infrared receiving mechanism 6 is installed on the shore side of the working area via the support rod 612 (the support rod 612 is inserted into the soil by applying an acting force via the pressure rod 613), the receiving head of the infrared receiving module U1 of the infrared receiving mechanism and the emitting head of the infrared emitting module U5 of the infrared emitting mechanism on one side end of the hull 8 are transversely in a straight line state facing each other; then an anchor rod is fixed on the other side of the shore, and the anchor rod is connected with the other side end of the ship body 8 through a rope (because the ship body can automatically control the direction in the subsequent process, the anchor rod rope only plays a limiting role, the acting force of the ship body on the anchor rod is small, and therefore the requirement on the ground soil environment of the shore is not large). When the invention works, the sand-pumping silt-pumping pump M pumps the water bottom sludge to the shore or other equipment for transporting silt and river sand after being electrified to work.
As shown in fig. 1, 2, 3 and 4, in the infrared receiving mechanism, after the power switch S is turned on, the power output by the battery G enters the two ends of the power output of the infrared receiving module U1 and the wireless transmitting module U2 of the infrared receiving mechanism, so that the infrared receiving module U1 and the wireless transmitting module U2 of the infrared receiving mechanism are in a power-on working state (after the battery G is without power, an external 12V power charger plug can be inserted into the charging socket CZ to charge the battery G). After a 220V alternating current power supply (one phase line and a zero line of a three-phase four-wire) enters pins 1 and 2 of a regulated power supply U3, a regulated power supply U3 outputs a stable 12V power supply under the action of an internal circuit of the regulated power supply U3, the stable 12V power supply enters two ends of a power supply input end of a wireless receiving module U4 and two ends of an infrared transmitting module U5, and then the wireless receiving module U4 and the infrared transmitting module U5 are in a power-on working state. After the infrared transmitting module U5 is powered on to work, a transmitting head of the infrared transmitting module U5 linearly transmits infrared beams, the infrared beams irradiate on a receiving head of an infrared receiving module U1 of an infrared receiving mechanism on the shore (the diameter of a convex lens is about 1 m, the focusing effect is achieved, the range of receiving infrared signals is larger), and under the effect of an internal circuit of the infrared receiving module U1 of the infrared receiving mechanism, 3 feet of the infrared receiving mechanism cannot output high level. When the ship body 8 drifts downwards due to the influence of water flow or the vibration of the ship body, an infrared beam emitted by the infrared emission module U5 positioned at one side end of the supporting frame is not received by the receiving head of the infrared receiving module U1 positioned at one side of the shore any more, so that the infrared receiving module U1 at one side of the shore can output high level to enter the positive power input end of the relay K1 due to the fact that 3 pins of the infrared beam cannot be received by the infrared receiving module U1 at one side of the shore, and then the relay K1 is electrified to attract the control contact end and the normally open contact end of the relay K1 to be closed; because the control contact end and the normally open contact end of the relay K1 are respectively connected with the two contacts under the SK key of the first wireless signal emission key of the wireless emission circuit module U2, at the moment, the wireless emission circuit module U2 emits a first path of wireless closing signals; when the infrared beam emitted by the infrared emitting module U5 on one side end of the supporting frame is received by the infrared receiving module U1 on one side of the shore again, the infrared receiving module U1 on one side of the shore stops outputting high level to enter the positive power input end of the relay K1 due to receiving 3 pins of the infrared beam, so that the relay K1 loses power and does not attract the control contact end and the normally open contact end to open, and then the wireless emitting circuit module U2 does not emit a first path of wireless closing signal.
As shown in fig. 1, 2, 3 and 4, when the boat body 8 moves downward with water flow during operation, the wireless transmitting circuit module U2 transmits a first wireless closing signal, the wireless receiving circuit module U4 receives the first wireless closing signal, then 4 feet of the wireless receiving circuit module U4 outputs a high level, the high level is subjected to voltage reduction and current limitation through the resistor R1 and enters the base of the NPN triode Q, then the NPN triode Q is conducted, the collector of the NPN triode Q outputs a low level and enters the negative power input end of the relay K2, the relay K2 is powered to attract the three control power input ends and the three normally open contact ends of the relay K2 to be respectively communicated, because the 380V alternating current power supply and the input end of the control power supply of the relay K2 are respectively connected through the conducting wires, the normally open contact end of the relay K2 is respectively connected with the two input ends of the power supplies of the two sets of electric propellers M1 and M2 through the conducting wires, therefore, at the moment, the two sets of electric propellers M1 and M2 can be electrified to work simultaneously and push the ship body 8 to move forwards; when the ship body moves forwards, after the infrared transmitting module U5 works by being electrified, the transmitting head of the infrared transmitting module U5 linearly transmits infrared beams and irradiates the receiving head of the infrared receiving module U1 of the infrared receiving mechanism on the shore again, and when 3 pins of the infrared receiving module U1 cannot output high level (the relay K1 is not electrified and is not closed any more), the wireless transmitting circuit module U2 stops transmitting a wireless closing signal; the wireless receiving circuit module U4 can not receive the wireless closing signal, so the relay K2 loses power, and then the two sets of electric propellers M1 and M2 do not work any more, and the ship body 8 stays in the working area to work. Under the action of all the circuits, when the ship drifts downwards due to the influence of water flow or the vibration of the ship, the ship can be automatically controlled to move forwards and be always in an operation area to operate under the combined action of the infrared transmitting mechanism and the infrared receiving mechanism. In fig. 3, 4, the resistance R1 is 1K; relay K2 is a DC12V relay; the NPN transistor Q model is 9013.
