Description

Technical Field

[0001] The present invention relates to the technical field of waterlogging drainage, and more specifically, to a combined emergency waterlogging drainage device and a working method thereof. Background Art

[0002] In recent years, due to climate change, rainfall in most places has increased, especially in the summer rainy season, which is very prone to floods and waterlogging. Due to the different terrains in cities and rural areas, the requirements for flood control and drainage work are different. In some places, the amount of water that forms waterlogging is large, and large displacement is required for rapid drainage, while in some places, high-lift long-distance drainage or remote water supply is required; and the existing drainage equipment is basically a power source driving a water pump to operate, and the displacement and lift of a single water pump are fixed. When large displacement and rapid drainage are required, only multiple drainage equipment can be operated at the same time, so the drainage equipment takes up more space, and is not very suitable in some places with narrow terrain, and the transportation of multiple drainage equipment is also inconvenient; when large-lift long-distance drainage is required, it can only be combined with a pressurizing device on the existing drainage equipment to increase the lift of the drainage equipment, as recorded in Chinese patent CN210842757U. Therefore, the existing drainage equipment cannot meet the working requirements of different flood control and drainage or remote water supply at the same time, which brings great inconvenience to flood control and drainage work. Summary of the invention

[0003] In order to overcome the problem that the existing drainage equipment cannot meet the requirements of different flood control and drainage work at the same time, which brings great inconvenience to flood control and drainage work, the present invention provides a combined emergency drainage equipment and a working method thereof. The present invention can meet the requirements of different flood control and drainage work at the same time, bringing great convenience to flood control and drainage work.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a combined emergency drainage equipment, including a power source, a clutch gearbox whose input shaft is connected to the power source, and a water pump connected to the output shaft of the clutch gearbox, wherein the number of output shafts of the clutch gearbox is at least two, each output shaft is clutch-driven connected to the input shaft, each output shaft is correspondingly connected to a water pump, and each output shaft can be independently switched forward and reverse. In this way, it is possible to realize that a power source drives multiple water pumps to operate in series or in parallel at the same time, and the direction of the water inlet and outlet can also be changed. And the output shaft and input shaft connected to the water pump are clutch-driven connected, so the number of water pumps actually operating can be determined according to actual needs, that is, although the combined emergency drainage equipment of the present application can realize that a power source drives multiple water pumps to operate at the same time, when multiple water pumps do not need to operate at the same time, the transmission between the output shaft and the input shaft corresponding to other water pumps can also be disengaged, leaving only one water pump to operate. In addition, each output shaft of the clutch gearbox can be independently switched to forward and reverse rotation, that is, when multiple water pumps are operating at the same time, the water delivery directions of the multiple water pumps can be the same or opposite, so that the series and parallel connection between multiple water pumps can be realized. When large-displacement drainage is required and the head is low, multiple water pumps operating at the same time can be operated in parallel, so that the total displacement of the drainage equipment is the sum of the displacements of the multiple water pumps operating at the same time, and rapid drainage can be achieved in a short time; when high-lift long-distance drainage is required, multiple water pumps operating at the same time can be connected in series, so that the total head of the drainage equipment is the sum of the heads of the multiple water pumps operating at the same time, and long-distance drainage can be achieved. In this way, the combined emergency drainage equipment of the present application can meet the different drainage operation requirements of large-displacement drainage and long-distance drainage at the same time, and the combined emergency drainage equipment of the present application has only one power source and one clutch gearbox, which greatly saves floor space, can adapt to more terrains, and brings great convenience to flood control and drainage work.

[0005] Furthermore, the power source is connected to the input shaft of the clutch gearbox through a universal coupling, and the water pump is connected to the output shaft of the corresponding clutch gearbox through a universal coupling. The universal coupling connection can ensure stable power output between the power source and the water pump.

[0006] Furthermore, each output shaft is provided with a clutch for disengaging the transmission between the output shaft and the input shaft. In this way, when a water pump needs to be disengaged from the operation, the corresponding clutch can be directly controlled to disengage the transmission between the corresponding output shaft and the input shaft, which is convenient and quick.

[0007] Furthermore, a main controller is included which is connected to the power source, the clutch gearbox and the clutch respectively. In this way, the start-up of the power source, the forward and reverse adjustment of each output shaft of the clutch gearbox, and the disengagement and closing of the clutch can be automatically controlled by the main controller, saving manpower.

[0008] Preferably, the power source is a diesel engine. Since floods and waterlogging are usually accompanied by power outages, choosing a diesel engine as a power source can make the combined emergency drainage equipment of the present application more adaptable and completely independent of electricity.

[0009] Furthermore, the water pump is a volumetric pump.

[0010] Furthermore, the power source, clutch gearbox and water pump are arranged on the same transport vehicle, which is more convenient for transportation.

[0011] Furthermore, a traction frame is provided at one end of the transport trolley, and lifting and fixing feet are provided at the four corners of the transport trolley. The traction frame can facilitate the tractor to transport the transport trolley, and the lifting and fixing feet can make the combined emergency drainage equipment have better stability when working.

[0012] The present invention also provides a working method of the combined emergency drainage device, which comprises the following steps:

[0013] S1. Determine the number of water pumps required for drainage work according to drainage task requirements, and disconnect the transmission between the output shaft and the input shaft of the water pumps that do not need to be used for drainage work;

[0014] S2. When the number of water pumps required for drainage is greater than 1, determine whether the combination of water pumps used for drainage is in series or in parallel according to the drainage task requirements, and use pipelines to complete the combination of water pumps used for drainage;

[0015] S3. Start the power source, which drives the water pump used for drainage through the clutch gearbox to perform drainage operations. After the drainage operation is completed, turn off the power source.

[0016] Furthermore, in step S2, when the drainage task requires draining a large amount of water in a short period of time, the combination of the water pumps used in the drainage work is selected in parallel to increase the drainage volume per unit time after the water pumps are combined; when the drainage task requires long-distance drainage, the combination of the water pumps used in the drainage work is selected in series to increase the head of the water pumps after the combination.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Each output shaft of the clutch gearbox of the present invention can be independently switched to forward and reverse rotation, so that multiple water pumps can be connected in series and in parallel. When large-displacement drainage is required, multiple water pumps operating at the same time can be connected in parallel, so that the total displacement of the drainage equipment is the sum of the displacements of the multiple water pumps operating at the same time, and rapid drainage can be achieved in a short time; when large-lift long-distance drainage is required, multiple water pumps operating at the same time can be connected in series, so that the total lift of the drainage equipment is the sum of the lifts of the multiple water pumps operating at the same time, and long-distance drainage can be achieved. In this way, the combined emergency drainage equipment of the present application can meet the different drainage operation requirements of large-displacement drainage and long-distance drainage at the same time, and the combined emergency drainage equipment of the present application only brings great convenience to flood control and drainage work.

[0019] The present invention can realize that one power source drives multiple water pumps to operate at the same time, and the output shaft and input shaft corresponding to each water pump are connected by a clutch transmission, so the number of water pumps actually operating can be determined according to actual needs, and there is only one power source and one clutch gearbox, which greatly saves floor space and can adapt to more terrains.

[0028] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0029] Example 1

[0030] like Figure 1 As shown, a combined emergency drainage device includes a power source 1, a clutch gearbox 2 whose input shaft 201 is connected to the power source 1, and a water pump 3 connected to the output shaft 202 of the clutch gearbox 2, wherein the number of output shafts 202 of the clutch gearbox 2 is two, each output shaft 202 is clutch-drivenly connected to the input shaft 201, and each output shaft 202 is detachably connected to a corresponding water pump 3, which is a first water pump and a second water pump, respectively, and each output shaft 202 can be independently switched to forward and reverse. In this way, one power source 1 can drive two water pumps 3 to work at the same time, and the output shaft 202 corresponding to the water pump 3 and the clutch gearbox 2 is detachably connected, so that the number of water pumps 3 actually working can be determined according to actual needs, that is, although the combined emergency drainage device of the present application can realize that one power source 1 drives two water pumps 3 to work at the same time, when the two water pumps 3 do not need to work at the same time, one of the water pumps 3 can be disconnected from the output shaft 202 corresponding to the clutch gearbox 2, leaving only the other water pump 3 to work. In addition, each output shaft 202 of the clutch gearbox 2 can be independently switched to forward and reverse rotation, that is, when the two water pumps 3 are operating at the same time, the water delivery directions of the two water pumps 3 can be the same or opposite, so the two water pumps 3 can be connected in series or in parallel. When a large-displacement drainage is required, the two water pumps 3 operating at the same time can be connected in parallel, so that the total displacement of the drainage equipment is the sum of the displacements of the two water pumps 3 operating at the same time, which can achieve rapid drainage in a short time; when a large-lift long-distance drainage is required, the two water pumps 3 operating at the same time can be connected in series, so that the total lift of the drainage equipment is the sum of the lifts of the two water pumps 3 operating at the same time, which can achieve long-distance drainage. In this way, the combined emergency drainage equipment of the present application can meet the different drainage operation requirements of large-displacement drainage and long-distance drainage at the same time, and the combined emergency drainage equipment of the present application has only one power source 1 and one clutch gearbox 2, which greatly saves floor space, can adapt to a variety of terrains, and brings great convenience to flood control and drainage work. In practical applications, such as Figures 2 to 7As shown, no matter a single water pump 3 is working, or two water pumps 3 are working in series or in parallel, the water delivery direction has two directions, positive and negative, and can be appropriately selected according to actual needs.

[0031] like Figure 1 As shown, the power source 1 is connected to the input shaft 201 of the clutch gearbox 2 through the universal coupling 4, and the water pump 3 is connected to the corresponding output shaft 202 of the clutch gearbox 2 through the universal coupling 4. The universal coupling 4 is used to ensure stable output of power between the power source 1 and the water pump 3.

[0032] In this embodiment, each output shaft 202 is provided with a clutch for disengaging the transmission between the output shaft 202 and the input shaft 201. In this way, when one of the water pumps 3 needs to be disengaged from the operation, the clutch can be directly controlled to disengage, which is convenient and quick.

[0033] In this embodiment, the power source 1 is a diesel engine. Since floods and waterlogging are usually accompanied by power outages, choosing a diesel engine as the power source 1 can make the combined emergency drainage equipment of the present application more adaptable and completely independent of electricity.

[0034] In this embodiment, the water pump 3 is a volumetric pump.

[0035] like Figure 1 As shown, the power source 1, clutch gearbox 2 and water pump 3 are arranged on the same transport vehicle 5, which is more convenient for transportation.

[0036] like Figure 1 As shown, a traction frame 6 is provided at one end of the transport trolley 5, and lifting and fixing feet 7 are provided at the four corners of the transport trolley 5. The traction frame 6 can facilitate the tractor to transport the transport trolley 5, and the lifting and fixing feet 7 can make the combined emergency drainage equipment have better stability when working.

[0037] Example 2

[0038] This embodiment is similar to the embodiment 1, except that this embodiment further comprises a main controller connected to the power source 1, the clutch gearbox 2 and the clutch, respectively. Thus, the start-up of the power source 1, the forward and reverse rotation adjustment of each output shaft 202 of the clutch gearbox 2, and the disengagement and closing of the clutch can be automatically controlled by the main controller, saving manpower.

[0039] The structure and working principle of other parts of this embodiment are the same as those of embodiment 1.

[0042] S1. Determine the number of water pumps 3 that need to be put into drainage work according to drainage task requirements, and disengage the transmission between the output shaft 202 and the input shaft 201 of the water pump 3 that does not need to be put into drainage work;

[0043] S2. When the number of pumps 3 required for drainage work is greater than 1, the combination of pumps 3 for drainage work is determined in series or in parallel according to the drainage task requirements, and the combination of pumps 3 for drainage work is completed by pipes;

[0044] S3. Start the power source 1, which drives the water pump 3 engaged in drainage work through the clutch gearbox 2 to perform drainage work. After the drainage work task is completed, turn off the power source 1.

[0045] In this embodiment, in step S2, when the drainage task requires draining a large amount of water in a short time, the combination mode of the water pumps 3 used in the drainage work is selected in parallel to increase the drainage volume per unit time after the water pumps 3 are combined; when the drainage task requires long-distance drainage, the combination mode of the water pumps 3 used in the drainage work is selected in series to increase the head of the water pumps 3 after the combination.
