Description

Technical Field

[0001] The present invention relates to the field of fire pumps, in particular to a high-efficiency heat dissipation fire pump based on multi-mode water diversion. Background Art

[0002] Fire pumps are the core equipment of fire water supply systems. Their main function is to provide sufficient water pressure and water volume for fire fighting, ensuring that fire hydrants, sprinkler systems and other fire fighting facilities can play an effective role when a fire occurs. They are widely used in different fields. Among them, forest fire pumps are high-efficiency fire fighting equipment specially designed for the characteristics of forest fires. Their core function is to quickly provide high-pressure water flow under complex terrain and water source conditions to cope with the suddenness and spread of forest fires.

[0003] The existing forest fire pump adopts a backpack or hand-pull structure as a whole. The high-pressure relay water pump adopts a multi-stage centrifugal pump design. A single pump can achieve a head of 240 meters. The water delivery capacity is significantly improved when multiple pumps are connected in parallel. This design can break through the terrain restrictions of mountains, canyons, etc., and directly transport water from the pool to the fire point. However, in actual operation, when the water outlet check valve of the fire pump is completely closed, the water source in the pump itself will heat up rapidly. The high temperature will change the physical properties of the water and aggravate the thermal stress and aging of the material. It is very easy to cause internal failure of the fire pump for a long time, and the pump cannot operate without water, because the centrifugal pump needs to be primed before starting. The existing pump priming is mostly manual water filling, and manual water filling is required while observing the water filling situation in the pump. The overall efficiency is too low, and this startup delay may cause the fire to get out of control and expand, thereby indirectly delaying the development of firefighting operations.

[0004] In summary, the above structure closes the water outlet one-way valve for a long time during actual operation of the water source in the pump, which can easily lead to internal failure of the fire pump, and the efficiency of manual water injection is too low, which may cause the fire to get out of control and expand. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a high-efficiency heat-dissipating fire pump based on multi-mode water diversion, so as to solve the technical problems that the water outlet one-way valve in the pump is closed for a long time during actual operation, which can easily lead to internal failure of the fire pump, and the efficiency of artificial water injection is too low, which may cause the fire to get out of control and expand in scope.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a high-efficiency heat-dissipating fire pump based on multi-mode water diversion, comprising a pump body and a silencer assembly, wherein a flow control device is provided at the bottom end of the pump body, an inlet pipe is connected between one end of the flow control device and the silencer assembly, and a one-way overflow valve is provided on the upper portion of the inlet pipe of the silencer assembly;

[0007] An exhaust port is provided at the top of the silencer assembly, wherein a ball valve is provided at the exhaust port, an exhaust gas vacuum pumping assembly is provided at the bottom of the silencer assembly, and a water spray pipe is connected to one end of the exhaust gas vacuum pumping assembly, a first water pumping pipe is provided at the top of the pump body, an electric control valve is provided on the first water pumping pipe, and one end of the first water pumping pipe is connected to the exhaust gas vacuum pumping assembly.

[0008] By adopting the above technical solution, the exhaust gas vacuum assembly drives the air in the first water pumping pipe and the pump body to be discharged through the water spray pipe. Since one end of the first water pumping pipe is at the top of the pump body, when water is discharged from the water spray pipe, it means that the pump body is full of water. At this time, the water priming is completed with one click.

[0009] The water source enters the silencer assembly through the water inlet pipe and is then discharged from the silencer outlet of the silencer assembly. The discharged water is discharged to the bottom water inlet pipe through the flow control device and the one-way overflow valve. In this process, the water source in the pump body is in a flowing state and will not accumulate in the pump body, preventing it from heating up in the pump body for a long time and causing damage to the pump body.

[0010] The present invention is further configured such that a muffler water outlet and a muffler water inlet are provided on the muffler assembly, one end of the muffler water outlet is connected to a one-way overflow valve, and one end of the muffler water inlet is connected to a water inlet pipe.

[0011] Preferably, the water in the water inlet pipe flows into the cooling chamber through the action of the muffler water inlet, and then after the cooling chamber is full, it is discharged to the one-way overflow valve through the muffler water outlet, thereby realizing the circulation of water and preventing the water from staying inside the pump body.

[0012] The present invention is further configured such that the silencer assembly includes a silencer outer cylinder, a silencer inner cylinder and a cooling chamber, a silencer inner cylinder is arranged inside the silencer outer cylinder, and a cooling chamber is formed between the silencer outer cylinder and the silencer inner cylinder, and at the same time, one end of the silencer water outlet and the silencer water inlet are connected to the cooling chamber.

[0013] Preferably, the water source passing through the water inlet of the silencer will flow into the cooling chamber between the two. As the water source flows in, the cooling chamber will gradually be filled. In this process, the water source in the cooling chamber is used to effectively dissipate heat for the silencer assembly, and the water source is in a flowing state in the cooling chamber. Therefore, the water source in the cooling chamber is in a state of continuous circulation and replacement, thereby further improving the heat dissipation effect of the silencer assembly. The arrangement of the silencer inner cylinder and the silencer outer cylinder utilizes the water source accumulated in the middle, which can effectively improve the overall silencer effect of the silencer assembly.

[0014] The present invention is further configured such that a controller is provided on one side of the pump body, wherein an electric pull rod cooperating with the controller is provided at the silencer assembly, and a rotating rod cooperating with the electric pull rod is rotatably provided at the top of the silencer assembly, and the rotating rod is provided in cooperation with the ball valve at the exhaust port.

[0015] Preferably, at startup, by pressing the controller, the electric pull rod will drive the rotating rod to rotate, thereby rotating the ball valve at the exhaust port so that the exhaust port is in a sealed state, facilitating the subsequent exhaust vacuum pumping component to perform vacuuming work.

[0016] The present invention is further configured such that a second water pumping pipe is provided on the first water pumping pipe, wherein the second water pumping pipe is located on both sides of the electric control valve, and a manual valve is rotatably provided on the second water pumping pipe.

[0017] Preferably, when the electric control valve on the first water pumping pipe fails, the manual valve on the second water pumping pipe is manually opened to connect the second water pumping pipe with the first water pumping pipe. At the same time, the pull rope is manually pulled to rotate the ball valve in the exhaust port to seal the exhaust port. In this process, when the electric control valve fails, water can be diverted manually, thereby improving the practicality of the device in complex working environments.

[0018] The present invention is further configured such that a pump water inlet is provided on one side of the pump body, and a water outlet one-way valve is provided on the other side.

[0019] As a preferred embodiment, when working, the water inlet of the pump is connected to the external water pipe to draw water from the outside and then discharge it through the water outlet one-way valve.

[0020] The present invention is further configured such that the electric control valve is electrically connected to the controller, and the electric control valve is detachably arranged on the first water pumping pipe.

[0021] Preferably, when the staff presses the controller, the pump body itself is in the starting state and the electric control valve is opened, which makes it convenient for the exhaust vacuum component to extract the water and air inside the pump body. The detachable setting makes it convenient for subsequent staff to regularly maintain and replace the electric control valve, thereby improving the overall service life.

[0022] The present invention is further configured such that a pressure gauge is provided on the top of the pump body located on the first water pumping pipe, and the pressure gauge is used to monitor the pressure condition in the pump body in real time.

[0023] Preferably, a pressure gauge is used to visually see the pressure conditions inside the pump body when the exhaust gas vacuum assembly is working, effectively preventing the water inlet from being blocked during the vacuum process, which may cause rupture inside the pump body, thereby increasing the overall service life of the pump body.

[0024] The present invention is further configured such that the output end of the electric pull rod is connected to a pull rope, the other end of the pull rope is connected to the rotating rod, one end of the rotating rod is elastically connected to a wedge block, and the wedge block is fixedly arranged at the top of the silencer assembly.

[0025] Preferably, the electric pull rod pulls the pull rope at the output end downward through the action of the controller. At this time, the pull rope will drive the rotating rod to rotate, thereby causing the ball valve in the exhaust port to rotate to complete the sealing of the exhaust port. After the subsequent water diversion is completed, the electric pull rod will reset itself. At this time, the pull rope will be reset under the action of the elastic component, and the ball valve will rotate accordingly. At this time, the exhaust port is in an open state.

[0026] The present invention is further configured such that both ends of the first water extraction pipe are sealed to the pump body and the tail gas vacuum extraction component respectively.

[0027] Preferably, when performing the vacuuming operation, air leakage is prevented from occurring, thereby affecting the normal progress of the water diversion operation.

[0028] In summary, the present invention mainly has the following beneficial effects:

[0029] 1. The present invention provides a flow control device at the bottom of the pump body. When the water outlet one-way valve is completely closed, the pump body continues to work, and the water inside it is discharged to the bottom water inlet pipe through the flow control device. In this process, the water in the pump body is in a flowing state and will not accumulate in the pump body, thereby preventing the water from heating up in the pump body for a long time and causing damage to the pump body. At the same time, the water enters the silencer assembly through the water inlet pipe and is then discharged from the water outlet of the silencer assembly. In this process, the water in the pump body circulates through the silencer assembly when the water outlet one-way valve is closed, thereby ensuring the pressure in the pump body is stable and cooling the silencer assembly.

[0030] 2. When the present invention is started, by pressing the controller, the electric pull rod drives the ball valve at the exhaust port to a closed state, and water is input into the pump body through the water inlet. At this time, the tail gas vacuum assembly works, and under the action of the tail gas vacuum assembly, the air in the first water pumping pipe and the pump body is driven to be discharged through the water spray pipe. Since one end of the first water pumping pipe is at the top of the pump body, when water is discharged from the water spray pipe, it means that the pump body is full of water. At this time, the water diversion is completed with one button. In this process, there is no need for manual water injection, which speeds up the starting efficiency of the pump body and facilitates the rapid development of fire extinguishing operations.

[0031] 3. The present invention divides the silencer assembly into an outer silencer cylinder and an inner silencer cylinder. The water source passing through the water inlet of the silencer will flow into the cooling chamber between the two. As the water source flows in, the cooling chamber will gradually be filled. In this process, the water source in the cooling chamber is used to effectively dissipate heat for the silencer assembly. The water source is in a flowing state in the cooling chamber, so the water source in the cooling chamber is in a state of continuous circulation and replacement, thereby further improving the heat dissipation effect of the silencer assembly. The arrangement of the inner silencer cylinder and the outer silencer cylinder utilizes the water source accumulated in the middle, which can effectively improve the overall silencer effect of the silencer assembly.

DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0046] The following describes an embodiment of the present invention based on its overall structure.

[0047] Example 1: Please refer to Figures 1-9 The high-efficiency heat dissipation fire pump based on multi-mode water diversion shown in the figure includes a pump body 1, an oil tank 2, a silencer assembly 8, a circulation mechanism, a water diversion mechanism and a heat dissipation mechanism, wherein the oil tank 2 is located at one end of the pump body 1, and the silencer assembly 8 is located on one side of the oil tank 2. The staff moves the device as a whole to the designated area. Since a pump water inlet 4 is provided on one side of the pump body 1 and a water outlet one-way valve 3 is provided on the other side, when diverting water, the pump water inlet 4 is connected to the external water pipe, and then the controller 12 on one side is started, and the silencer assembly An exhaust port 9 is provided at the top of 8, wherein a ball valve 19 is provided at the exhaust port 9, and a pull rope is connected to the output end of the electric pull rod 7, the other end of which is connected to the rotating rod 15, and a wedge block is elastically connected to one end of the rotating rod 15, and the wedge block is fixedly provided at the top of the muffler assembly 8. When the electric pull rod 7 pulls the pull rope at the output end downward under the action of the controller 12, the pull rope will drive the rotating rod 15 to rotate, thereby rotating the ball valve 19 at the exhaust port 9 to complete the sealing work of the exhaust port 9;

[0048] At the same time, an exhaust gas vacuum pumping assembly 18 is provided at the bottom of the muffler assembly 8, and a water spray pipe 6 is connected to one end of the exhaust gas vacuum pumping assembly 18. A first water pumping pipe 5 is provided on the top of the pump body 1, and an electric control valve 10 is provided on the first water pumping pipe 5. A controller 12 is provided on one side of the fuel tank 2. When the staff presses the controller 12 to guide water, the electric control valve 10 is in an open state, and one end of the first water pumping pipe 5 is connected to the exhaust gas vacuum pumping assembly 18. At this time, the pump draws water from the outside at the water inlet 4 into the interior of the pump body 1, and the exhaust gas vacuum pumping assembly 18 works. , driving the air in the first water pumping pipe 5 and the pump body 1 to be discharged through the water spray pipe 6. Since one end of the first water pumping pipe 5 is at the top of the pump body 1, when water is discharged from the water spray pipe 6, it means that the pump body 1 is full of water. At this time, the one-key water priming is completed. No manual water filling is required in this process, which speeds up the starting efficiency of the pump body 1 and facilitates the rapid development of fire extinguishing operations. After the subsequent water priming is completed, the electric pull rod 7 will reset itself. At this time, the pull rope is reset under the action of the elastic component, and the ball valve 19 rotates accordingly. At this time, the exhaust port 9 is in an open state;

[0049] Then the staff releases the controller 12, the electric control valve 10 is in the closed state, and the electric pull rod 7 releases the limit on the rotating rod 15, so that the ball valve 19 at the exhaust port 9 is reset and rotated, and the seal inside the exhaust port 9 is released. At this time, the pump body 1 works normally, water enters through the pump water inlet 4, and then drains through the water outlet check valve 3, ensuring that the fire extinguishing work proceeds as usual;

[0050] When the staff turns off the water outlet, the pump body 1 itself does not stop working, and the water inlet continues to take in water. However, a flow control device 13 is provided at the bottom end of the pump body 1, and an inlet pipe 14 is connected between one end of the flow control device 13 and the silencer assembly 8, and a one-way overflow valve 11 is provided on the upper part of the inlet pipe 14 of the silencer assembly 8. When the water outlet one-way valve 3 is closed, the water in the pump body 1 will be discharged into the inlet pipe 14 through the flow control device 13. In this process, the water in the pump body 1 is in a flowing state and will not accumulate in the pump body 1, preventing it from heating up in the pump body 1 for a long time and causing damage to the pump body 1. At the same time, the water in the inlet pipe 14 will flow into the interior of the silencer assembly 8, and then be discharged from the silencer assembly 8 through the one-way overflow valve 11. In this process, the water in the pump body 1 is circulated through the silencer assembly 8 when the water outlet one-way valve 3 is closed, ensuring the pressure in the pump body 1 is stable and the silencer assembly 8 can be cooled and dissipated.

[0051] In the above embodiment, please refer to Figure 6The silencer assembly 8 is provided with a muffler water outlet 20 and a muffler water inlet 21. One end of the muffler water outlet 20 is connected to the one-way overflow valve 11, and one end of the muffler water inlet 21 is connected to the water inlet pipe 14. Through the action of the muffler water inlet 21, the water in the water inlet pipe 14 flows into the silencer assembly 8. After the inner wall of the silencer assembly 8 is filled, it is discharged to the one-way overflow valve 11 through the muffler water outlet 20, thereby realizing the circulation of the water source and preventing the water source from staying inside the pump body 1.

[0052] In the above embodiment, please refer to Figure 4 and Figure 5 A pressure gauge 22 is provided on the first water pumping pipe 5 at the top of the pump body 1. The pressure gauge 22 is used to monitor the pressure situation inside the pump body 1 in real time. The pressure gauge 22 is convenient for visually viewing the pressure situation inside the pump body 1 when the exhaust gas vacuum pumping component 18 is working, effectively preventing the pump body 1 from being broken when the water inlet 4 of the pump is blocked during the vacuum pumping process, thereby improving the overall service life of the pump body 1.

[0053] Example 2: Please refer to Figure 10 The shown embodiment is a high-efficiency heat dissipation fire pump based on multi-mode water diversion, the overall structure of which is similar to that of Example 1, wherein a second water pumping pipe 16 is provided on the first water pumping pipe 5, wherein the second water pumping pipe 16 is located on both sides of the electric control valve 10, and a manual valve 17 is rotatably provided on the second water pumping pipe 16. When the electric control valve 10 on the first water pumping pipe 5 fails, the pump body 1 is manually started, and then the manual valve 17 on the second water pumping pipe 16 is opened, so that the second water pumping pipe 16 and the first water pumping pipe 5 are in a connected state. At the same time, the pull rope is manually pulled to rotate the ball valve 19 at the exhaust port 9 to seal the exhaust port 9, and then the exhaust gas vacuum assembly 18 works to discharge the gas in the pump body 1, the first water pumping pipe 5 and the second water pumping pipe 16 through the water spray pipe 6 until water is sprayed out of the water spray pipe 6. In this process, when the electric control valve 10 fails, water can be diverted manually, thereby improving the practicality of the device in complex working environments.

[0054] In the above embodiment, please refer to Figure 10 The electric control valve 10 and the controller 12 are electrically connected, and the electric control valve 10 is detachably arranged on the first water pumping pipe 5. When the staff presses the controller 12, the pump body 1 itself is in the starting state, and the electric control valve 10 is opened, which facilitates the exhaust vacuum component 18 to extract the water and air inside the pump body 1. The detachable arrangement facilitates subsequent staff to regularly maintain and replace the electric control valve 10, thereby improving the overall service life.

[0055] Example 3: Please refer to Figure 11The illustrated embodiment is a high-efficiency heat dissipation fire pump based on multi-mode water diversion, based on the second embodiment, wherein the silencer assembly 8 includes a silencer outer cylinder 801, a silencer inner cylinder 802 and a cooling chamber 803, wherein the silencer outer cylinder 801 is provided with a silencer inner cylinder 802, and a cooling chamber 803 is formed between the silencer outer cylinder 801 and the silencer inner cylinder 802, and at the same time, the silencer water outlet 20 and one end of the silencer water inlet 21 are connected to the cooling chamber 803, and the water source passing through the silencer water inlet 21 will flow into the cooling chamber 803 between the two. As the water source flows in, the cooling chamber 803 will be gradually filled. In this process, the water source in the cooling chamber 803 is used to effectively dissipate heat for the silencer assembly 8 as a whole;

[0056] In addition, the water source is in a flowing state in the cooling chamber 803, so the water source in the cooling chamber 803 is in a state of continuous circulation and replacement, thereby further improving the heat dissipation effect of the silencer assembly 8, and the water source accumulated in the silencer inner cylinder 802 and the silencer outer cylinder 801 will always be in a full state, and the water in the cooling chamber 803 is in a flowing state. The sound waves will drive the water molecules to vibrate, and the inertia and viscous resistance of the water will convert the vibration energy into heat energy, thereby realizing the dissipation of sound energy, thereby effectively improving the overall sound insulation effect of the silencer assembly 8 during the working process.

[0057] The present invention works specifically as follows: when in use, the staff presses the controller 12 to make the electric pull rod 7 pull the rotating rod 15 to rotate, thereby making the ball valve 19 at the exhaust port 9 in a closed state. At this time, the tail gas vacuum pumping assembly 18 works. Since the exhaust port 9 of the muffler assembly 8 is in a closed state, the tail gas vacuum pumping assembly 18 will discharge the gas in the first water pumping pipe 5 and the pump body 1 through the water spray pipe 6. At the same time, the pump water inlet 4 of the pump body 1 will draw water from an external water source to inject water into the pump body 1. Since one end of the first water pumping pipe 5 is at the top of the pump body 1, when water is discharged from the water spray pipe 6 during the process of the tail gas vacuum pumping assembly 18 exhausting the vacuum, it means that the inside of the pump body 1 has been filled with water. At this time, the water diversion is completed with one button. No manual water injection is required during this process, which speeds up the starting efficiency of the pump body 1 and facilitates the rapid development of fire extinguishing operations.

[0058] At the same time, when the water outlet one-way valve 3 is closed during operation, the pump body 1 will still be in a working state. During this process, the pump body 1 will continue to draw water, and the water inside it will be discharged to the water inlet pipe 14 through the flow control device 13 at the bottom, effectively preventing the water in the pump body 1 from malfunctioning due to overheating, and the water is discharged outward through the muffler outlet 20 of the muffler assembly 8, so that the water source can flow in the muffler assembly 8, while ensuring the stability of the pressure in the pump body 1, and being able to cool the muffler assembly 8.

[0059] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
