Description

Technical Field

[0001] The present application relates to the field of water pumps, and in particular to a water pump and a fire station. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids, and is mainly used to transport liquids. Generally, a large-volume and high-flow water pump is fixedly installed on the island. Usually, the water pump connected to the water pump is placed in the seawater to extract the seawater, and then discharged through the outlet pipe connected to the water pump for fire fighting.

[0003] During the operation of the water pump, the marine garbage and aquatic weed impurities in the seawater will be adsorbed into the water pump due to the suction force, thereby affecting the normal operation of the water pump. In the related art, people will install a filter on the water pump pipe.

[0004] With respect to the above-mentioned related technologies, the inventors believe that marine debris and aquatic plant impurities can easily clog the filter screen on the pumping pipe, thereby affecting the efficiency of the pumping operation. Summary of the invention

[0005] In order to improve the efficiency of water pumping operations, the present application provides a water pump and a fire station.

[0006] In the first aspect, the present application provides a water pump, which adopts the following technical solution:

[0007] A water pump, comprising:

[0008] A pump body, wherein a water suction pipe is installed at the water inlet of the pump body;

[0009] The conversion mechanism comprises a conversion shell connected to the water pumping pipe, a plurality of water suction pipes rotatably installed in the conversion shell and connected to the water pumping pipe, and a driving motor for driving the plurality of water suction pipes to rotate, and an insertion hole for inserting the water suction pipe is provided on the outer wall of the conversion shell;

[0010] The filter mechanism comprises a filter housing arranged on the conversion housing, a filter plate rotatably mounted on the filter housing, and a rotation driving member driving the filter plate to rotate, a filter hole is provided on a side of the filter housing close to the filter plate, and the filter housing is connected to the plug hole;

[0011] The collecting mechanism comprises a collecting box, a sliding door slidably mounted on the collecting box, and a sliding driving member for driving the sliding door to slide. A collecting groove is provided on one side of the collecting box. The sliding door is located on the side of the collecting box where the collecting groove is provided to cover or open the groove opening of the collecting groove. The rear cover of the filter plate is rotated and is arranged at the groove opening of the collecting groove.

[0012] By adopting the above technical solution, when the pump body is pumping water, the conversion mechanism, the filtering mechanism and the collecting mechanism are all located in the water, and the filter shell cover is arranged at the plug hole of the conversion shell. Larger garbage in the seawater cannot enter the filter shell due to the action of the filter plate. When a lot of garbage is accumulated at the filter plate, the rotating drive member will drive the filter plate to rotate, and at this time the sliding drive member drives the sliding door to open, and the filter plate will move the garbage to the collection tank for collection, preventing the garbage from accumulating at the filter plate again.

[0013] When some smaller garbage such as water plants pass through the filter plate and the filter shell and block the suction pipe inserted into the plug hole, the driving motor drives multiple suction pipes to rotate, so that another suction pipe is inserted into the plug hole to continue pumping water, thereby improving the pumping efficiency of the water pump.

[0014] Optionally, a placement cavity is opened on one side of the conversion shell, a water box is rotatably arranged in the placement cavity, a plurality of water suction pipes are installed on the water box and connected with the inside of the water box, the water suction pipe is connected with the water box, and a cover plate is provided at the cavity opening of the placement cavity.

[0015] By adopting the above technical solution, the water suction pipe draws water from the outside of the conversion shell and then enters the water storage box. The water inside the water storage box is discharged through the suction pipe. When the suction pipe is inserted into the plug hole during conversion, it is ensured that there is always water in the water storage box, thereby reducing the risk of the suction pipe failing to pump out water during rotation.

[0016] Optionally, the water suction pipe includes a filter head and a bellows, and a driving cylinder for driving the filter head to insert into or detach from the plug hole is provided on the outer wall of the water storage box, and the bellows is connected to the inside of the water storage box.

[0017] By adopting the above technical solution, the filter head can filter the garbage entering the filter shell for the second time, reducing the risk of garbage entering the pump body. When the suction pipe needs to be switched, the driving cylinder drives the filter head to disengage from the plug hole, and the bellows shrinks at this time, thereby reducing the risk of interference between the filter head and the switching shell when the water box rotates.

[0018] Optionally, the water pump also includes a filter box arranged on the shore, a backwash hole for inserting the suction pipe is opened on the conversion shell, a branch water pipe is inserted into the backwash hole, the end of the branch water pipe away from the conversion shell is connected to the filter box, a water distribution pipe is arranged on the side of the filter box away from the branch water pipe, and the end of the water distribution pipe away from the filter box is connected to the suction pipe.

[0019] By adopting the above technical solution, when the filter head is clogged with garbage, the driving motor drives the water box to rotate, so that the clogged filter head is inserted into the backwash hole. Under the action of the pump body suction, the water in the water box will enter the filter box from the branch pipe. In this process, the garbage on the filter head will be washed into the filter box, and people only need to clean the garbage in the filter box regularly. Therefore, during the operation of the pump body, cleaning the clogged filter head is relatively automatic.

[0020] Optionally, a plurality of filter screens are detachably provided in the filter box, and the plurality of filter screens are arranged at intervals along the direction in which water flows from the branch water pipe into the water distribution pipe.

[0021] By adopting the above technical solution, on the one hand, multiple filter screens play a role of filtering layer by layer, reducing the risk of garbage entering the pump body; on the other hand, when cleaning, one filter screen is removed, and the remaining filter screens still maintain the filtering effect, and there is no need to stop the pump body for cleaning, thereby improving the operating efficiency of the pump body when pumping water.

[0022] Optionally, a sliding groove is provided in the filter box, and the filter is slidably installed in the sliding groove.

[0023] By adopting the above technical solution, the filter screen can be conveniently installed on the filter box without closing the pump body.

[0024] Optionally, the mesh number of the filter head is greater than the mesh number of the filter plate.

[0025] By adopting the above technical solution, the risk of garbage entering the pump body is further reduced.

[0026] Optionally, a side of the filter plate facing away from the filter shell is provided with an annular convex edge, and after the filter plate is rotated, the convex edge is inserted into the collecting groove.

[0027] By adopting the above technical solution, when the filter plate rotates to push the garbage into the collection box, the convex edge limits the garbage on the filter plate and reduces the risk of garbage floating.

[0028] Optionally, the collection box is provided with a water permeable hole connected to the collection tank.

[0029] By adopting the above technical solution, when the collection box is brought ashore, the water inside the collection box can be discharged through the water-permeable holes, thereby reducing the weight of the collection box.

[0030] In a second aspect, the present application provides a water pump, which adopts the following technical solution:

[0031] A mobile fire station comprises the above-mentioned water pump and a mobile vehicle, wherein the water pump is installed on the mobile vehicle.

[0032] By adopting the above technical solution, the water pump can be moved on the island with the mobile vehicle, thereby improving the convenience of moving the water pump. At the same time, it is also convenient to move the water pump when extinguishing a fire, thereby pressurizing the water flow and extending the range of the water jet.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] When a lot of garbage is accumulated on the filter plate, the rotating drive member will drive the filter plate to rotate. At this time, the sliding drive member drives the sliding door to open, and the filter plate will move the garbage to the collection tank for collection, preventing the garbage from being accumulated on the filter plate again.

[0035] When some smaller garbage such as water plants pass through the filter plate and the filter shell and block the water suction pipe inserted into the plug hole, the driving motor drives the multiple water suction pipes to rotate, so that another water suction pipe is inserted into the plug hole to continue pumping water, thereby improving the water pumping efficiency;

[0036] When the filter head is clogged with garbage, the driving motor drives the water box to rotate, and then the clogged filter head is inserted into the backwash hole. Under the action of the pump body suction, the water in the water box will enter the filter box from the branch pipe. In this process, the garbage on the filter head will be washed into the filter box. People only need to clean the garbage in the filter box regularly. In the process of pump body operation, cleaning the clogged filter head is relatively automatic. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-6 This application is described in further detail.

[0045] The present application embodiment discloses a water pump. Figure 1 The water pump includes a pump body 1, a conversion mechanism 2, a filter mechanism 3, a collection mechanism 4 and a filter box 5. The pump body 1 and the filter box 5 are both located on the shore, and the conversion mechanism 2, the filter mechanism 3 and the collection mechanism 4 are all located underwater. When the pump body 1 is in operation, the filter mechanism 3 filters the garbage and aquatic plants in the seawater. The collection mechanism 4 is connected to the filter mechanism 3, and the garbage filtered by the filter mechanism 3 will be stored in the collection mechanism 4, thereby reducing the risk of the garbage being always located at the filter mechanism 3 and affecting the pumping efficiency. The conversion mechanism 2 is connected to the filter mechanism 3, and some of the garbage passes through the filter mechanism 3 and adheres to the conversion mechanism 2. The conversion mechanism 2 rotates and cooperates with the pump body 1 to backwash the garbage attached to the conversion mechanism 2 into the filter box 5 without affecting the flow rate of water entering the pump body 1.

[0046] Reference Figure 1 and Figure 2 The pump body 1 is provided with a plurality of water inlets and a plurality of water outlets, and the number of the water outlets is consistent with the number of the water inlets and corresponds one to one. A water suction pipe 11 is installed at the water inlet by bolts, and seawater enters the pump body 1 through the water suction pipe 11 and is discharged from the water outlet. Assuming that the conversion mechanism 2, the filtering mechanism 3, the collecting mechanism 4 and the filter shell 31 are filtering devices, the number of filtering devices is consistent with the number of water inlets and corresponds one to one, and the filtering device is installed on the side of the water suction pipe 11 away from the pump body 1. The following is an example of a filtering device for explanation.

[0047] Reference Figure 2 and Figure 3The conversion mechanism 2 includes a conversion shell 21, a plurality of water suction pipes 22 and a driving motor 23. The conversion shell 21 is installed at one end of the water suction pipe 11 away from the pump body 1 and is connected to the water suction pipe 11. The plurality of water suction pipes 22 are rotatably installed in the conversion shell 21 through the driving motor 23. When one of the water suction pipes 11 is blocked and affects the water flow, the other unblocked water suction pipe 22 will rotate to the water suction position to continue to absorb water.

[0048] A placement cavity 211 is provided on one side of the conversion shell 21, and a water box 24 is installed in the placement cavity 211. A rotating column is integrally formed on the side of the water box 24 close to the bottom of the placement cavity 211, and a rotating groove for inserting the rotating column is provided on the bottom of the placement cavity 211. The driving motor 23 is installed on the side of the conversion shell 21 away from the placement cavity 211, and the motor shaft of the driving motor 23 is inserted into the rotating column, thereby driving the water box 24 to rotate.

[0049] Reference Figure 2 and Figure 3 The water box 24 has a water storage cavity inside. The peripheral wall of the water box 24 is provided with a plurality of water inlet holes connected to the water storage cavity at intervals and evenly. The number of the water inlet holes is consistent with the number of the water suction pipes 22 and corresponds to each other. One end of the water suction pipe 22 is inserted into the water inlet hole and fixedly installed on the water box 24, and the water suction pipe 22 can be extended and retracted in the placement cavity 211. The outer wall of the conversion shell 21 is provided with a plug hole 212 connected to the placement cavity 211 and for any one of the water suction pipes 22 to be inserted. The water suction pipe 22 is inserted into the plug hole 212 and protrudes from the conversion shell 21 to extract seawater. The water box 24 is provided with a water outlet hole on the side away from the bottom of the placement cavity 211. The water outlet hole is connected to the water storage cavity, and the water extraction pipe 11 is inserted into the water outlet hole. With the above structure, when the water box 24 rotates to replace the water suction pipe 22 inserted into the plug hole 212, water can be stored in the water chamber all the time, thereby reducing the risk of water flow interruption in the water extraction pipe 11. A cover plate 213 is installed at the opening of the placement chamber 211 by bolts to limit the water box 24 in the placement chamber 211, and the water extraction pipe 11 will pass through the cover plate 213 when installed.

[0050] Reference Figure 3 In detail, the water suction pipe 22 includes a filter head 221 and a bellows 222, and the filter head 221 and the bellows 222 are integrally formed. The bellows 222 is inserted into the water inlet hole, and the filter head 221 is inserted into the plug hole 212 to filter the absorbed seawater, thereby reducing the risk of garbage entering the water box 24. The outside of the water box 24 is bolted with a driving cylinder 25, and the outer wall of the filter head 221 is fixedly installed with a support ear, and the telescopic rod of the driving cylinder 25 is fixedly installed on the support ear, thereby controlling the filter head 221 to be inserted into or pulled out of the plug hole 212.

[0051] The filter mechanism 3 includes a filter shell 31, a filter plate 32 and a rotating drive member 33. The filter shell 31 is fixedly mounted on the outer wall of the conversion shell 21, and the filter shell 31 is covered at the plug hole 212 and communicated with the plug hole 212, thereby filtering the garbage without affecting the water absorption of the filter head 221. The rotating drive member 33 drives the filter plate 32 to rotate, and pushes away the garbage attached to the filter plate 32 due to suction, so that the garbage enters the collection mechanism 4, thereby reducing the risk of garbage blocking the filter plate 32. It is worth noting that the mesh number of the filter plate 32 is smaller than the mesh number of the filter head 221, and the garbage entering the filter shell 31 can be filtered twice through the filter head 221.

[0052] Reference Figure 2 and Figure 4 , a plurality of filter holes 311 are provided on the side of the filter shell 31 away from the conversion shell 21, and the filter plate 32 is located on the side of the filter shell 31 where the filter holes 311 are provided, and the side of the filter plate 32 close to the filter shell 31 abuts against the filter shell 31. A filter plate rotation hole is provided on one side of the filter plate 32 along the placement cavity 211, and the filter plate rotation hole penetrates the filter plate 32. Two rotating ears 312 are integrally formed on the side of the filter shell 31 abutting against the filter plate 32, and the two rotating ears 312 are arranged at intervals and through holes are provided on the two rotating ears 312, and the two through holes are arranged concentrically with the filter plate rotation hole. The filter plate 32 is located between the two rotating ears 312, and a rotating shaft 321 is inserted into one of the through holes, and one end of the rotating shaft 321 passes through the rotating hole of the filter plate 32 and is rotated and inserted into the other through hole. The rotating shaft 321 passes through the hole of the filter plate 32 and is fixedly connected to the filter plate 32 by welding, but the rotating shaft 321 is rotatably connected with the two rotating ears 312.

[0053] Reference Figure 2 and Figure 4 , the side of the rotating shaft 321 close to the cover plate 213 protrudes from the rotating ear 312, and the part of the rotating shaft 321 protruding from the rotating ear 312 is sleeved with a first bevel gear, and the first bevel gear is fixedly mounted on the rotating shaft 321. In this embodiment, the rotating driving member 33 is preferably a motor, wherein the rotating driving member 33 is bolted to the side of the filter housing 31 close to the cover plate 213, and a second bevel gear meshing with the first bevel gear is fixedly mounted on the rotating shaft 321 of the rotating driving member 33. The rotating driving member 33 runs, driving the second bevel gear to rotate, and the second bevel gear meshes with the first bevel gear to drive the filter plate 32 to rotate.

[0054] A convex edge 322 is integrally formed on one side of the filter plate 32 away from the filter housing 31, and the convex edge 322 is in a closed loop shape. When the filter plate 32 rotates, the garbage located at the filter plate 32 is not easy to float away under the action of the convex edge 322.

[0055] Reference Figure 2 and Figure 4The collection mechanism 4 includes a collection box 41, a sliding door 42 and a sliding drive 43. The collection box 41 is fixedly mounted on a side of the filter housing 31 perpendicular to the filter plate 32 and close to the two rotating ears 312. The collection box 41 is provided with a collection slot 411 perpendicular to a side adjacent to the filter housing 31 and away from the conversion housing 21, and the sliding door 42 is slidably mounted at the notch of the collection slot 411. In this embodiment, the sliding drive 43 is preferably a cylinder, and the sliding drive 43 drives the sliding door 42 to move and open the collection slot 411. After the filter plate 32 rotates, the convex edge 322 can be inserted into the collection slot 411, thereby moving the garbage into the collection slot 411. When the filter plate 32 does not rotate, the sliding drive 43 drives the sliding door 42 to move, so that the sliding door 42 covers the notch of the collection slot 411, thereby reducing the risk of garbage escaping from the collection slot 411.

[0056] Among them, each groove wall and groove bottom of the collection groove 411 are provided with a plurality of water-permeable holes 412 penetrating the collection box 41. When the collection box 41 is salvaged ashore, seawater can flow out of the collection groove 411 through the water-permeable holes 412, thereby making it more convenient to salvage the collection box 41. A mounting plate 413 is welded and installed on the side of the collection box 41 away from the filter shell 31, and the sliding drive member 43 is fixedly installed on the mounting plate 413, and the piston rod of the sliding drive member 43 is fixedly connected to the sliding door 42. Through the above structure, when the sliding door 42 is opened, the side close to the filter shell 31 opens first, thereby facilitating the entry of garbage into the collection groove 411.

[0057] Reference Figure 1 and Figure 3 A backwash hole 214 communicating with the placement chamber 211 is provided on the outer wall of the conversion shell 21, and a branch water pipe 12 is inserted into the backwash hole 214. A flange is provided at one end of the branch water pipe 12 away from the conversion shell 21, and the flange is bolted to the filter box 5 so that the branch water pipe 12 communicates with the filter box 5. A water distribution pipe 13 communicating with the filter box 5 is installed on the side of the filter box 5 away from the connection with the branch water pipe 12, and the other end of the water distribution pipe 13 is fixedly installed on the water pumping pipe 11 and communicates with the water pumping pipe 11. When the clogged filter head 221 is rotated, it can be inserted into the backwash hole 214. At this time, under the action of the suction force of the pump body 1, part of the water flow in the water box 24 will backwash the clogged filter head 221, that is, the water flow in the water box 24 will impact the filter head 221 and impact the garbage or aquatic plants on the filter head 221 from the branch pipe 12 to the filter box 5 for filtration, and then the filtered water in the filter box 5 flows into the water suction pipe 11 through the water distribution pipe 13.

[0058] Reference Figure 5A filter tank 51 is provided on the top of the filter box 5, and the branch water pipe 12 and the water distribution pipe 13 are respectively located on opposite sides of the filter tank 51 and are both connected to the filter tank 51. A plurality of filter screens 52 are slidably installed in the filter tank 51, and the plurality of filter tanks 51 are arranged at intervals along the direction of the water flow from the branch water pipe 12 to the water distribution pipe 13. The garbage clogged on the filter head 221 is flushed into the filter tank 51 and filtered through the filter screen 52. At the same time, a sliding groove 53 for sliding installation of the filter screen 52 is provided on the tank wall of the filter tank 51, so that the filter screen 52 can be pulled out for cleaning, and it is also convenient to install it under the action of the sliding groove 53. A baffle is provided at the notch of the filter tank 51 to reduce the risk of garbage floating in the air entering the filter tank 51.

[0059] The implementation principle of a water pump in the embodiment of the present application is as follows: when pumping water is required, the pump body 1 is started, and under the action of the suction force of the pump body 1, seawater will enter the water box 24 from the filter head 221, and then enter the pump body 1 through the water pumping pipe 11. In this process, due to the suction force of the pump body 1, garbage in the seawater will gather at the filter plate 32. The rotating drive member 33 drives the filter plate 32 to rotate, and at the same time, the sliding drive member 43 drives the sliding door 42 to move so that the collection tank 411 is opened. After the filter plate 32 rotates, the garbage is moved to the collection tank 411 for collection. If some garbage enters the filter box 5 and blocks the filter head 221, the driving motor 23 will drive the water box 24 to drive the filter head 221 to rotate, so that the unblocked filter head 221 will be inserted into the plug hole 212 to continue pumping water; and the blocked filter head 221 will be inserted into the backwash hole 214, and the water in the water box 24 will backwash the blocked filter head 221, and the garbage in the flushing area will be filtered again through the filter net 52 located in the filter box 5.

[0060] The present application also discloses a mobile fire station. Figure 6 The mobile fire station includes the water pump and the mobile vehicle 6 in the above embodiment, wherein the pump body 1 and the filter box 5 are fixedly mounted on the mobile vehicle 6. When a fire occurs near the sea, the conversion mechanism 2, the filter mechanism 3 and the collection mechanism 4 can be placed on the mobile vehicle 6, and then the mobile vehicle 6 can be moved to the fire site to extinguish the fire.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
