Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] EMBODIMENT

[0021] Please refer to Figs. 1-3 The present application provides the following technical solutions:

[0022] A diesel engine start-stop device with remote control, comprising a diesel engine body 1, the diesel engine body 1 comprising a throttle electromagnetic valve, a pressure reduction electromagnetic valve and a starter switch, the throttle electromagnetic valve, the pressure reduction electromagnetic valve and the starter switch being electrically connected with a delay relay one, a delay relay two and a delay relay three respectively, the delay relay one, the delay relay two and the delay relay three being electrically connected with a receiver switch, the receiver switch being signal connected with a remote controller;

[0023] When the diesel engine water pump starts, the delay relay can control the starter switch, so that the starter drives the diesel engine crankshaft to rotate after a certain delay after the power is turned on, thus avoiding the impact of the instantaneous large current of the starter on the circuit and the starter itself, prolonging the service life of the starter, and also allowing the diesel engine parts to have a gradual stress process, reducing the wear between mechanical parts, and ensuring a more stable and safe starting process.

[0024] For the pressure reducing electromagnetic valve, the delay relay can keep it open for a certain period of time at the beginning of starting, reduce the initial pressure in the cylinder, facilitate smooth starting of the diesel engine, and after starting, the delay relay controls the pressure reducing electromagnetic valve to close, so that the diesel engine gradually enters the normal working pressure state, avoiding damage to the diesel engine parts caused by sudden pressure change, such as pistons, cylinder covers, etc., and ensuring the reliability and stability of the diesel engine.

[0025] The side surface of the diesel engine body 1 is fixedly provided with fixed blocks 2, the fixed blocks 2 are provided with hinge shafts 3, the middle positions of the hinge shafts 3 are fixedly connected with placing plates 4, one end surfaces of the hinge shafts 3 are fixedly connected with rotating rods 5, the front surface of the diesel engine body 1 is fixedly provided with blocking rods 6, the blocking rods 6 are overlapped with the side surfaces of the rotating rods 5, the lower surfaces of the placing plates 4 are provided with grooves, and the placing rods 8 are hingedly arranged in the grooves through pin shafts 7.

[0027] The working principle of the utility model is as follows:

[0028] 1, after the remote controller sends an opening instruction, the receiver switch receives a signal to turn on the main power switch to supply power to the delay relay one, the delay relay two and the delay relay three, the delay relay one, the delay relay two and the delay relay three respectively make the throttle electromagnetic valve attract to the preset throttle size, the pressure reducing electromagnetic valve attract to the pressure reducing state, and the starter switch starts to start, after the inertia speed rises, the pressure reducing delay relay two makes the pressure reducing electromagnetic valve de-energize to reset, after the diesel engine starts, the delay relay three de-energizes to stop the starter to complete the starting process, when stopping, the remote controller sends an instruction, the receiver switch receives a signal to de-energize the entire circuit, the throttle electromagnetic valve de-energizes to reset the throttle to the minimum, and then the diesel engine cuts off the oil to extinguish the fire and stop;

[0029] 2、In the process of installing the water pump, the placing plate 4 can be rotated to be parallel to the ground, the fixing of the placing plate 4 is completed through the overlapping of the rotating rod 5 and the blocking rod 6, at this time, the staff can place the accessories on the surface of the placing plate 4, and the placing rod 8 can also be rotated to hang the tools on the surface of the placing rod 8.
