Description
Technical Field
[0001] This invention relates to the field of fire pumps, specifically to a diesel water supply pump for fire extinguishing and its usage method. Background Technology
[0002] Diesel water pumps for fire extinguishing are a common type of fire-fighting equipment, playing an important role, especially in situations where power supply is unstable or in field fire-fighting scenarios. They have high power output, do not require an external power source, can work for a long time when fuel is plentiful, have a robust structure, and are highly adaptable to the environment (high temperature, humidity, etc.). They are suitable for extinguishing large fires and are often used in remote areas, forests, and field fires. When working in deep forests and in the wild, water pumps are usually directly connected to rivers and lakes to draw water. Due to the complex environment in the wild, the water often contains leaves, debris, mud, and other substances. These leaves and debris enter the water pump with the water flow, easily causing wear and blockage of the pump impeller and affecting the water supply. The traditional method is to add a filter screen to the water inlet pipe to block leaves and debris. When too many leaves and debris accumulate, it is often necessary to stop the water pump, clean the filter screen, and then continue working. In order to facilitate the separation of leaves and debris and improve work efficiency, a fire extinguishing diesel water pump and its usage method are proposed. Summary of the Invention

The inlet pipe and the separation pipe constitute the leaf separation mechanism of the water pump inlet pipe. The connecting mechanism and the sealing gate constitute the leaf discharge mechanism in the separation pipe. The storage box and the cleaning mechanism are used to store and clean the separated leaves.
[0005] Preferably, the separation pipe includes a pipe body, a limiting base, and a barrier net. The two ends of the pipe body are connected to the water inlet pipe through flange structures, the limiting base is fixed inside the pipe body, and the barrier net is installed obliquely on the side of the limiting base.

[0011] Preferably, the scraper is provided with side shovels at both ends, and the top surface of the side shovels is set as an inclined surface.
[0012] A method for using a diesel water supply pump for fire extinguishing includes the following steps: Step S1: Connect the water outlet at the top of the water pump body to the water outlet pipe; Step S2: Install the pipe body between the two inlet pipe sections; Step S3: Connect the inlet pipe to the pumping pipe; Step S4: Insert the sealing gate into the fixed slot, adjust the position of the gate body to make the inside of the discharge pipe closed, and make the top surface of the gate body fit with the bottom surface of the sealing ring. Step S5: Fit the connector at the top of the box to the bottom of the discharge pipe to fix the storage box to the bottom of the connecting mechanism; Step S6: Install the cleaning mechanism from the side of the box, so that the cover is tightly against the opening on the side of the box, and seal the box. Step S7: Start the fuel engine to drive the water pump body.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention includes a support base with a fuel engine on top. A water pump body is connected to the fuel engine's output end. A separator pipe is installed on the side of the water pump body, and a connecting mechanism is located at the bottom of the separator pipe. A sealing gate is inserted into the side of the connecting mechanism, and a storage tank is connected to the bottom of the connecting mechanism. A cleaning mechanism is installed on the side of the storage tank. An inlet pipe is located on the side of the water pump body, and the separator pipe is installed in the middle of the inlet pipe. The inlet pipe and separator pipe constitute a leaf separation mechanism for the water pump's inlet pipe. The connecting mechanism and the sealing gate constitute a leaf extraction mechanism within the separator pipe. The storage tank and cleaning mechanism are used to store and clean the separated leaves. In use, the water pump body is driven by the fuel engine. The system operates by drawing water into the pump body through the inlet pipe and outputting it through the outlet pipe at the top of the pump body. Before entering the pump body, the water passes through a separation pipe, which blocks leaves and debris mixed in with the water. By adjusting the position of the sealing gate in the connecting mechanism, when the connecting mechanism is open, the leaves and debris in the separation pipe enter the storage tank through the connecting mechanism. Then, the sealing gate closes the connecting mechanism, and finally, the cleaning mechanism removes the leaves and debris from the storage tank. During firefighting, the pump can be cleaned without stopping the pump, preventing leaves and debris from entering the pump and causing blockages, thus improving the progress of firefighting and increasing work efficiency. 2. This invention also includes a separation pipe, comprising a pipe body, a limiting base, and a barrier net. Both ends of the pipe body are connected to the inlet pipe via flange structures. The limiting base is fixed inside the pipe body, and the barrier net is installed obliquely on the side of the limiting base. The barrier net is fixed by the limiting base, allowing it to be in an inclined state inside the pipe body, facilitating water flow to wash the surface of the barrier net and making it easier to remove leaves and debris blocked by the barrier net. A baffle plate is provided at the end of the gate body, with two sets of baffle plates respectively located on the top and bottom surfaces of the gate body. The baffle plates are vertically fixed to the gate body. The baffle plates abut against the side of the sealing ring, ensuring the discharge pipe remains sealed when the gate body is pulled out of the fixed slot. Side scrapers are provided at both ends of the scraper, with the top surface of the side scrapers being an inclined surface. The side scrapers clean the inner surfaces of the box, preventing debris from adhering inside the box and affecting the scraper extraction process. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0017] Example: like Figure 1 - Figure 8 As shown, the present invention provides a fire extinguishing diesel water supply pump and its usage method, including a support base 1, a fuel engine 2 is provided on the top of the support base 1, a water pump body 3 is connected to the output end of the fuel engine 2, a separation pipe 4 is installed on the side of the water pump body 3, a connecting mechanism 5 is provided at the bottom of the separation pipe 4, a sealing gate 6 is inserted on the side of the connecting mechanism 5, a storage tank 7 is connected to the bottom of the connecting mechanism 5, and a cleaning mechanism 8 is installed on the side of the storage tank 7. The water pump body 3 has an inlet pipe 31 on its side, and a separator pipe 4 is installed in the middle of the inlet pipe 31. The inlet pipe 31 and the separator pipe 4 constitute the leaf separation mechanism of the water pump inlet pipe. The connecting mechanism 5 and the sealing gate 6 constitute the leaf discharge mechanism inside the separator pipe 4. The storage tank 7 and the cleaning mechanism 8 are used to store and clean the separated leaves. In use, the water pump body 3 is driven by the fuel engine 2. Water is drawn into the water pump body 3 through the inlet pipe 31 and discharged from the outlet pipe at the top of the water pump body 3. Before the water enters the interior of the water pump body 3, it first passes through... The separation pipe 4 blocks leaves and debris mixed in the water. By adjusting the position of the sealing gate 6 in the connecting mechanism 5, when the connecting mechanism 5 is open, the leaves and debris in the separation pipe 4 enter the storage tank 7 through the connecting mechanism 5. Then, the sealing gate 6 closes the connecting mechanism 5, and finally, the cleaning mechanism 8 removes the leaves and debris from the storage tank 7. During the fire extinguishing process, the leaves and debris can be cleaned without stopping the water pump, preventing leaves and debris from entering the water pump and causing blockage, which would affect the fire extinguishing progress and improve work efficiency.
[0018] The separation pipe 4 includes a pipe body 41, a limiting base 42, and a barrier net 43. The two ends of the pipe body 41 are connected to the water inlet pipe 31 through flange structures. The limiting base 42 is fixed to the inside of the pipe body 41. The barrier net 43 is installed at an angle on the side of the limiting base 42. The barrier net 43 is fixed by the limiting base 42, so that the barrier net 43 is in an inclined state inside the pipe body 41, which facilitates the water flow to wash the surface of the barrier net 43, making it easier to wash away the leaves and debris blocked by the barrier net 43.
[0019] The connecting mechanism 5 includes a discharge pipe 51, a fixing slot 52 and a sealing ring 53. The discharge pipe 51 is fixed to the bottom of the pipe body 41, the fixing slot 52 is opened on the side of the discharge pipe 51, and the sealing ring 53 is fixed to the inside of the discharge pipe 51 and is located on the top side of the fixing slot 52.
[0020] The sealing gate 6 includes a gate body 61 and limiting strips 62. The gate body 61 is inserted into the fixed slot 52. Two sets of limiting strips 62 are respectively disposed on both sides of the bottom surface of the gate body 61. The limiting strips 62 are inserted into the fixed slot 52 to limit the two sides of the gate body 61 and prevent displacement during the process of pulling the sealing gate 6.
[0021] A baffle plate 611 is provided at the end of the gate body 61. Two sets of baffle plates 611 are respectively provided on the top and bottom surfaces of the gate body 61. The baffle plates 611 are fixed vertically to the gate body 61. The baffle plates 611 abut against the side of the sealing ring 53, so that the discharge pipe 51 is kept sealed when the gate body 61 is pulled out of the fixing slot 52.
[0022] The storage box 7 includes a box body 71, a connection port 72, and a transparent window 73. The box body 71 is located at the bottom of the discharge pipe 51, the connection port 72 is located at the top of the box body 71, and the transparent window 73 is located on the side of the connection port 72. The amount of leaves and debris stored inside the box body 71 can be observed through the transparent window 73.
[0023] The cleaning mechanism 8 includes a cover plate 81, a limiting baffle 82, and a scraper 83. The cover plate 81 is installed at the side opening of the housing 71. Two sets of limiting baffles 82 are fixed to both ends of the inner side of the cover plate 81. The scraper 83 is fixed to the bottom of the end of the limiting baffle 82. The limiting baffles 82 limit the two sides of the cleaning mechanism 8, so that the cleaning mechanism 8 maintains its direction during the process of pulling out the housing 71.
[0024] The scraper 83 is provided with side scraper plates 831 at both ends. The top surface of the side scraper plate 831 is set as an inclined surface. The side scraper plate 831 cleans the inner two sides of the box 71 to prevent debris from adhering to the inside of the box 71 and affecting the scraper 83 extraction process.
[0025] A method for using a diesel water supply pump for fire extinguishing: Connect the water outlet at the top of the water pump body 3 to the water outlet pipe; install the pipe body 41 between the two sections of the inlet pipe 31; connect the inlet pipe 31 to the pumping pipe; insert the sealing gate 6 into the fixing slot 52, adjust the position of the gate body 61 so that the inside of the discharge pipe 51 is in a closed state, and make the top surface of the gate body 61 fit against the bottom surface of the sealing ring 53; fit the connection port 72 at the top of the box 71 onto the bottom of the discharge pipe 51, so that the storage box 7 is fixed to the bottom of the connecting mechanism 5; install the cleaning machine The cover plate 81 is installed from the side of the housing 71, so that it fits tightly against the opening on the side of the housing 71, sealing the housing 71; the fuel engine 2 is started, and the fuel engine 2 drives the water pump body 3 to run; water is drawn through the water inlet pipe 31, and the leaves and debris mixed in the water enter the pipe body 41 of the separator pipe 4 through the water inlet pipe 31; the leaves and debris entering the pipe body 41 with the water flow are blocked by the barrier net 43; when too many leaves and debris accumulate inside the pipe body 41, the sealing gate 6 is pulled, so that the gate body 61 moves along the solid... The fixed slot 52 moves outward from the discharge pipe 51, opening the inside of the discharge pipe 51. This allows the leaves and debris blocked by the barrier net 43 to be flushed into the discharge pipe 51 by the water flow, and then enter the storage box 7 through the discharge pipe 51. After the leaves and debris on the side of the barrier net 43 enter the storage box 7, they push the sealing gate 6 back into the discharge pipe 51, causing the discharge pipe 51 to close again. The amount of leaves and debris inside the box 71 can be observed through the transparent window 73. The cover plate 81 is pulled, and the contents of the cover plate 81 are then pulled... The limiting baffle 82 drives the scraper 83, which moves towards the opening on the side of the box 71, pushing out the leaves and debris stored inside the box 71, thus cleaning the leaves and debris inside the storage box 7. During the operation of the water pump, the sealing gate 6 is pulled and pushed back at regular intervals, allowing the leaves and debris inside the separation pipe 4 to enter the storage box 7. The amount of leaves and debris inside the storage box 7 is observed through the transparent window 73. Step S13 is repeated to complete the cleaning operation.
[0026] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
