Description

Technical Field

[0001] This disclosure relates to a water intake structure, a fire pump, and a fire truck. Background Technology

[0002] The maximum flow rate of existing bare fire pumps is 170 L / s (commonly known as a 10,000-liter pump, meaning a maximum flow rate of 10,000 L per minute, for example, 170 L / s × 60 s = 10,200 L). The maximum flow rate of a bare pump refers to the test flow rate when the fire pump is not installed on a fire truck. When a fire pump is installed on a fire truck, it needs to be matched with suction inlets, discharge outlets, and other connecting components to complete the water intake into the water tank or to supply water to the fire monitor for fire extinguishing. During installation and testing, the "installed flow rate" of the fire pump will differ from the "bare pump flow rate," and in most cases, the "installed flow rate" will be lower.

[0051] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0052] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0053] See Figure 1 The illustration shows a three-dimensional schematic diagram of the suction inlet structure 100 proposed in this disclosure. In this exemplary embodiment, the suction inlet structure 100 proposed in this disclosure is described with an example of its application to a fire pump. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of pumps, and these changes are still within the scope of the principles of the suction inlet structure 100 proposed in this disclosure.

[0054] like Figure 1As shown, in one embodiment of this disclosure, according to one aspect of this disclosure, the suction port structure 100 proposed in this disclosure is used for installation on a pump (e.g., a fire pump), and the suction port structure 100 includes a first suction pipe 110, a second suction pipe 120, an intermediate pipe 130, and a connecting pipe 140. The first suction pipe 110 and the second suction pipe 120 are arranged vertically at intervals. The first suction pipe 110 has three first suction ports 111 on one side along the first horizontal direction X, and the three first suction ports 111 are arranged along a second horizontal direction Y perpendicular to the first horizontal direction X, and the axis of the first suction ports 111 extends along the first horizontal direction X. The second suction pipe 120 has two second suction ports 121 on the same side of the first horizontal direction X (relative to the same side of the first suction ports 111), and the two second suction ports 121 are arranged along a second horizontal direction Y perpendicular to the first horizontal direction X, and the axis of the second suction ports 121 extends along the first horizontal direction X. An intermediate pipe 130 connects the first suction pipe 110 and the second suction pipe 120, and at least part of the intermediate pipe 130 extends vertically. One end of a connecting pipe 140 is connected to the first suction pipe 110, and the other end of the connecting pipe 140 is used to connect to the pump inlet. Through the above structural design, this disclosure increases the number of suction ports in the suction port structure 100 and arranges the suction ports on two vertically spaced suction pipes. This fully utilizes the suction capacity of the fire pump, alleviates the flow loss problem during fire pump loading operations, increases the flow rate of the water system during loading operations, and improves fire extinguishing efficiency. At the same time, this disclosure, through the reasonable arrangement of the pipe structures, occupies less space, making it suitable for application scenarios with limited space in the fire truck water pump room, and is easy to implement.

[0055] See Figures 2 to 4 As shown, Figure 2 The diagram shows a perspective view of the intake structure 100, which embodies the principles of this disclosure, in another exemplary embodiment. Figure 3 China representatively shows Figure 2 The front view; Figure 4 China representatively shows Figure 2 Side view.

[0056] Different from Figures 1 to 3 The illustrated implementation uses a "three-on-top, two-on-bottom" intake arrangement, such as... Figures 2 to 4 As shown, in one embodiment of this disclosure, the first suction pipe 110 is provided with three first suction ports 111, and the second suction pipe 120 may be provided with only one second suction port 121, i.e., a "three on top, one on bottom" suction port arrangement is adopted. Through the above structural design, while maintaining a relatively large number of suction ports in the suction port structure 100, this disclosure reduces the number of second suction ports 121 provided in the second suction pipe 120, which is further suitable for application in the small water pump room of a fire truck.

[0057] Specifically, the applicant for Figures 2 to 4 The suction port structure 100 shown was subjected to flow rate testing. The test results showed that, for the above-mentioned "three on top and one on the bottom" suction port arrangement, when the three first suction ports 111 were opened individually, the flow rate of the test system pipeline could reach 162 L / s. When the second suction port 121 was opened, the flow rate of the test system pipeline could reach 160 L / s. It can be seen that the above-mentioned test flow rate is close to the maximum flow rate of the bare pump (e.g., 170 L / s). Therefore, the suction port structure 100 in the above embodiment can alleviate the flow loss problem of fire pump installation to a certain extent.

[0058] like Figure 3 As shown, in one embodiment of this disclosure, the intermediate pipe 130 and the connecting pipe 140 can be arranged offset along the second horizontal direction Y. Specifically, the connection position between the intermediate pipe 130 and the first suction pipe 110 can be located in the area between two adjacent first suction ports 111. The connecting pipe 140 is connected to the first suction pipe 110 and indirectly connected to the intermediate pipe 130 via the first suction pipe 110. Furthermore, the connection position between the connecting pipe 140 and the first suction pipe 110 corresponds to the position of the first suction pipe 110 located in the middle along the second horizontal direction Y.

[0059] See Figure 5 and Figure 6 As shown, Figure 5 The diagram shows a perspective view of the intake structure 100, which embodies the principles of this disclosure, in another exemplary embodiment. Figure 6 China representatively shows Figure 5 The front view.

[0060] Different from Figures 2 to 4 The illustrated embodiment uses a design where the intermediate pipe 130 is connected to the first suction pipe 110, as shown in the example. Figure 5 and Figure 6 As shown, in one embodiment of this disclosure, taking the above-mentioned "three upper and one lower" water inlet arrangement as an example, the intermediate pipe 130 can be directly connected to the connecting pipe 140.

[0061] like Figure 5 and Figure 6 As shown, in one embodiment of this disclosure, along the second horizontal direction Y, the orthographic projection of the second water inlet 121 on the horizontal plane corresponds to the orthographic projection of the first water inlet 111 located in the middle on the horizontal plane.

[0062] like Figure 5 and Figure 6As shown, in one embodiment of this disclosure, the connection position between the intermediate pipe 130 and the first water suction pipe 110 along the second horizontal direction Y corresponds to the position of the first water suction port 111 located in the middle along the second horizontal direction Y.

[0063] like Figure 5 and Figure 6 As shown, in one embodiment of this disclosure, along the second horizontal direction Y, the connection position of the intermediate pipe 130 and the second water suction pipe 120 is arranged corresponding to the position of the second water suction port 121.

[0064] See Figures 7 to 9 As shown, Figure 7 The diagram shows a perspective view of the intake structure 100, which embodies the principles of this disclosure, in another exemplary embodiment. Figure 8 China representatively shows Figure 7 The front view; Figure 9 China representatively shows Figure 7 Side view.

[0065] Different from Figures 1 to 6 The illustrated implementation schemes use "three on top and two on the bottom" and "three on top and one on the bottom" suction inlet arrangements, such as... Figures 7 to 9 As shown, in one embodiment of this disclosure, the first suction pipe 110 may have only one first suction port 111, and the second suction pipe 120 may have three second suction ports 121, i.e., a "top-bottom-three" suction port arrangement. Through the above structural design, the three second suction ports 121 are arranged on the lower side. This arrangement allows the water flow at the convergence point of the three second suction ports 121 to achieve "stable flow" due to the gravity effect caused by the height difference. The flow rates of the three second suction ports 121 can stably converge at the intermediate pipe 130 and then merge with the first suction pipe 110.

[0066] Specifically, the applicant for Figures 7 to 9The suction inlet structure 100 shown was subjected to flow rate testing. The test results showed that, for the above-mentioned "top-bottom-three" suction inlet arrangement, when one first suction inlet 111 and three second suction inlets 121 were all open, the flow rate of the test system pipeline could reach 167 L / s. This indicates that the tested flow rate is closer to the maximum flow rate of the bare pump (e.g., 170 L / s). Therefore, the suction inlet structure 100 in the above embodiment can further alleviate the flow loss problem during fire pump installation. Furthermore, in the above flow rate test, the flow rate when all four suction inlets were open was not less than the flow rate when only three second suction inlets 121 were open. This indicates that the above-mentioned "top-bottom-three" suction inlet arrangement can effectively solve the "turbulence phenomenon" at the water pipe connection (water turbulence phenomenon usually refers to the phenomenon of water flow generating vortices, turbulence, or other irregular flows due to changes in water flow velocity, changes in pipe shape, or the influence of other obstacles when water flows through pipes or other water systems), avoiding adverse effects on the efficiency and function of the water system.

[0067] like Figures 7 to 9 As shown, in one embodiment of this disclosure, the connecting pipe 140 includes a first connecting portion 141 and a second connecting portion 142. One end of the first connecting portion 141 is connected to the first suction pipe 110, and one end of the second connecting portion 142 is connected to the intermediate pipe 130. The other ends of the first connecting portion 141 and the second connecting portion 142 converge to form an interface 143, which is used to connect to the inlet of the fire pump.

[0068] like Figures 7 to 9 As shown, in one embodiment of this disclosure, the first connecting part 141 can be a bent tube, which bends upward and connects to the first suction pipe 110, so that the interface 143 is closer to the second suction port 121 in the vertical direction than the first suction port 111. The second connecting part 142 can be a bent tube, which bends downward and connects to the intermediate pipe 130. Accordingly, the interface 143 is offset from the first suction port 111 and the second suction port 121 in the vertical direction, that is, the interface 143 is lowered to a lower position relative to the first suction port 111, and the water flow convergence point of the first suction pipe 110 and the second suction pipe 120 (i.e., the convergence point of the first connecting part 141 and the second connecting part 142) is slightly lower than the first suction pipe 110.

[0069] See Figure 10 and Figure 11 As shown, Figure 10 The image shows a front view of the intake structure 100, which embodies the principles of this disclosure, in another exemplary embodiment; Figure 11 China representatively shows Figure 10 Side view.

[0070] Different from Figures 7 to 9The illustrated embodiment employs a recessed design at the confluence of the first suction pipe 110 and the second suction pipe 120, as shown in 12 and Figure 11 As shown, in one embodiment of this disclosure, taking the above-described "one-one-three" suction port arrangement as an example, the point where the water flows from the first suction pipe 110 and the second suction pipe 120 converge (i.e., the point where the first connecting part 141 and the second connecting part 142 converge) can be arranged horizontally. In other words, the interface 143 corresponds to the first suction port 111 in the vertical direction. Specifically, the first connecting part 141 is a straight pipe and extends along the first horizontal direction X, so that the interface 143 and the first suction port 111 are arranged in a vertically corresponding manner. The second connecting part 142 is a bent pipe, which bends downward and connects to the intermediate pipe 130.

[0071] Specifically, the applicant for Figure 10 and Figure 11 The suction port structure 100 shown was subjected to flow rate testing. The test results showed that for the above-mentioned "one top and three bottom" suction port arrangement, when one first suction port 111 and three second suction ports 121 are all open, the flow rate of the test system pipeline can reach 170L / s, which is the maximum flow rate of the bare pump. Therefore, the suction port structure 100 in the above embodiment can significantly alleviate the flow loss problem during fire pump installation and is suitable for maximizing the pump's suction capacity.

[0072] like Figure 10 and Figure 11 As shown, in one embodiment of this disclosure, the orthographic projection of the second water inlet 121 located in the middle along the second horizontal direction Y on the horizontal plane can be arranged correspondingly to the orthographic projection of the first water inlet 111 on the horizontal plane.

[0073] like Figure 10 and Figure 11 As shown, in one embodiment of this disclosure, the connection position of the intermediate pipe 130 and the second suction pipe 120 along the second horizontal direction Y corresponds to the position of the second suction port 121 located in the middle along the second horizontal direction Y.

[0074] like Figure 10 and Figure 11 As shown, in one embodiment of this disclosure, along the second horizontal direction Y, the connection position between the intermediate pipe 130 and the first water suction pipe 110 is arranged corresponding to the position of the first water suction port 111.

[0075] In some embodiments of this disclosure, the first water inlet 111 may be provided with a connecting flange to facilitate connection with other pipelines or interfaces.

[0076] In some embodiments of this disclosure, the second water inlet 121 may be provided with a connecting flange to facilitate connection with other pipelines or interfaces.

Based on this, the sum of the number of first suction ports 111 and second suction ports 121 is three or more. Furthermore, one end of the connecting pipe 140 is connected to at least one of the first suction pipe 110 and the intermediate pipe 130, and the other end of the connecting pipe 140 is used to connect to the inlet of the fire pump 200.

[0079] Furthermore, in Figures 2 to 11 In the various embodiments shown, the number of first water inlets 111 is not equal to the number of second water inlets 121, with the smaller number being one and the larger number being three.
