Technical Field
[0001] The utility model relates to the technical field of cotton pickers, and particularly relates to a fire-fighting water device for a cotton picker. Background Art
[0002] When the existing cotton pickers are performing large-scale cotton picking operations, due to factors such as long-term high-load operation of the equipment and accumulation of cotton dust, there is a certain fire risk. And the existing cotton pickers generally lack fire-fighting facilities. Once a fire breaks out, it is often impossible to extinguish it in time by manually holding a fire extinguisher, resulting in equipment damage and even causing farmland fires. Therefore, it is necessary to design a fire-fighting water device for a cotton picker to effectively control the fire risk on the machine body without excessive cost. Content of the Utility Model

[0005] A fire-fighting water device for a cotton picker, comprising a water tank, a check valve, a filter, a water pump, a five-way joint, a normally closed waterproof solenoid valve and a spray head connected in sequence by a connecting pipe. The five communication ports of the five-way joint are respectively communicated with the water pump, two groups of working pipelines, the normally closed waterproof solenoid valve and a water pressure sensor. The normally closed waterproof solenoid valve and the spray head are connected by a connecting pipe to form a fire-fighting pipeline. The fire-fighting pipeline is fixed to the machine body by a bracket, and the spray head is arranged around the machine body.
[0006] Preferably, the check valve is connected to a sealing head through a connecting pipe, and the sealing head is communicated with a water outlet arranged on the water tank.
[0007] Preferably, a fire-fighting water gun is further arranged on the fire-fighting pipeline near the spray head.
[0008] Preferably, the number of the spray heads is set to be multiple, and they are evenly distributed around the machine body.
[0009] Preferably, the normally closed waterproof solenoid valve and the connecting pipe are connected by a 24° taper seal structure.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. On the basis of the original working pipeline, the utility model adds fire-fighting appliances such as a five-way joint, a normally-closed waterproof solenoid valve, and a sprinkler head, that is, a new fire-fighting water line is added at the working water use of the cotton picker, sharing a power source with the working water. The modified structure is simple, saving costs. The opening and closing of the fire-fighting pipeline water is controlled by the solenoid valve, which has a fast response, precise control, and a stable and reliable structure.
[0012] 2. The utility model strengthens the sealing effect, making it more stable and having a low failure rate by setting a sealing head at the water outlet of the water tank and adopting a 24° taper sealing structure at both ends of the solenoid valve. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for describing the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.
[0014] Figure 1 It is a schematic structural diagram of the fire-fighting water device of the cotton picker of the present utility model.
[0015] Among them, 1 - water tank, 2 - water outlet, 3 - sealing head, 4 - check valve, 5 - filter, 6 - water pump, 7 - five-way joint, 8 - normally-closed waterproof solenoid valve, 9 - sprinkler head, 10 - fire hose, 11 - connecting pipe, 12 - working pipeline, 13 - fire-fighting pipeline, 14 - water pressure sensor. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0017] The technical solutions of the present utility model will be further described below with reference to the drawings. Figure 1A cotton picker fire fighting water device is shown, which includes a water tank 1, a check valve 4, a filter 5 and a water pump 6 connected in sequence by a connecting pipe 11. It also includes a five-way joint 7, a normally closed waterproof solenoid valve 8 and a spray head 9. The five communication ports of the five-way joint 7 are respectively communicated with the water pump 6, two groups of working pipelines 12, the normally closed waterproof solenoid valve 8 and a water pressure sensor 14. When testing the water pressure in the pipeline, the water pressure sensor 14 gives the water pressure reading in the pipeline, which is used to calibrate the water pump 6 so that the water pressure meets the power demand of fire fighting water. The normally closed waterproof solenoid valve 8 and the spray head 9 are connected by a connecting pipe 11 to form a fire fighting pipeline 13. The fire fighting pipeline 13 is fixed to the machine body by a bracket, and the spray head 9 is arranged around the machine body. It can be seen that on the original working water pipeline, by adding a five-way joint, a new fire fighting water path is added, which shares a power source with the working water. The modified structure is simple, the cost is saved, and when a fire is excluded, the opening and closing of the fire fighting pipeline water is controlled by the solenoid valve, which has a fast response, precise control and a stable and reliable structure.
[0018] On the fire fighting pipeline 13, the existing dry fire extinguishing sprinkler system can also be used for further modification. However, in this way, the structure becomes complicated, and at the same time, the cost is increased, but the ability to pre-control the fire situation is also enhanced.
[0019] In order to enhance the sealing effect at the water outlet 2 of the water tank 1, make the water outlet more stable, and adapt to the increased water pressure after adding fire fighting water, the check valve 4 is connected to the sealing head 3 through a connecting pipe 11, and the sealing head 3 is connected to the water outlet 2 provided on the water tank 1. This makes the sealing effect better and the failure rate lower.
[0020] In order to facilitate manual fire fighting, a fire fighting water gun 10 is also provided on the fire fighting pipeline 13 near the spray head 9. Hold the fire fighting water gun 10 to extinguish the fire, increasing the fire fighting activity range.
[0021] The number of spray heads 9 is set to be multiple, and they are evenly distributed around the machine body to complete the coverage of fire hazard areas.
[0022] The normally closed waterproof solenoid valve 8 and the connecting pipe 11 are connected by a 24° taper seal joint and tightened with a nut. This 24° taper seal structure has a better sealing effect, is more stable, and has a lower failure rate.
[0023] The working principle of the present utility model:
[0024] Such as Figure 1As shown in the figure, after the water pump 6, a five-way joint 7 is used to newly connect a connecting pipe 11 outside the two groups of working pipelines 12 to a normally closed waterproof solenoid valve 8, and then the normally closed waterproof solenoid valve 8 is connected to the nozzles 9 around the cotton collecting box and the handheld fire hose 10. The connecting pipe 11 of this part constitutes a fire pipeline 13 for adapting to the fire extinguishing requirements of the machine body. Usually, the normally closed waterproof solenoid valve 8 is closed. When a fire breaks out, the normally closed waterproof solenoid valve 8 is opened, and the water in the water tank 1 passes through the filter 5 to the water pump 6, and is pressurized by the water pump 6 to the fire pipeline 13 for fire extinguishing treatment.
[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
