Description

Technical Field

[0001] This utility model relates to the technical field of drainage emergency vehicles, specifically a high-flow drainage emergency vehicle with adjustable drainage pipes. Background Technology

[0002] During extreme weather events such as typhoons, cities experience heavy rainfall, which puts a sudden increase in pressure on municipal pipe networks. Accumulated rainwater cannot be quickly drained into rivers or the sea in a short period of time, which can easily lead to flooding, especially at underpasses where water can accumulate, making passage impossible and even submerging vehicles. Timely drainage is necessary.

[0003] The existing Chinese utility model patent with publication number CN212401028U discloses a drainage emergency vehicle. This vehicle includes a transport vehicle equipped with a guide rod and a moving cylinder. A drum support is mounted on the guide rod, and the moving cylinder is connected to the drum support. A water pipe guide arm is also located next to the drum on the transport vehicle. The guide arm has multiple guide wheels for guiding the water pipe, and a water pump is connected to the end of the water pipe on the guide arm. The guide arm can move the water pump to the perimeter of the transport vehicle. By setting up the water pipe guide arm, the water pipe and its connected water pump can be guided to the surface of the floodwater, facilitating rapid laying and arrangement of the water pipe, improving emergency response efficiency, and saving time. Furthermore, by setting baffles on the drum, different lengths of water pipe are wound between different adjacent baffles, allowing the drainage emergency vehicle to adapt to various drainage needs in different situations. The appropriate length of water pipe can be selected as needed, facilitating rapid deployment and improving efficiency.

[0004] The aforementioned drainage emergency vehicle uses a single water pump for drainage operations. Since the drainage capacity of a single water pump is limited, it is impossible to adjust the drainage volume according to the actual situation. Furthermore, in the initial stage of drainage operations, there is a certain amount of air inside the pipe. Because air is highly compressible, when the impeller pushes the mixture of air and liquid, the air will be compressed or expanded, resulting in unstable pressure inside the pump and an inability to form continuous drainage power. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable high-flow drainage emergency vehicle, which solves the problems of air inside the pipe affecting drainage operations in the initial stage of drainage and the inability to adjust the drainage volume.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-flow-rate adjustable drainage emergency vehicle includes a tractor unit, and a drainage mechanism is provided above the tractor unit.

[0007] The adjustment component is located above the tractor and is used to adjust the position of the water inlet end of the pipeline structure.

[0008] The drive assembly includes a volute centrifugal pump fixedly mounted above the tractor. A tee is fixedly mounted at the water inlet of the volute centrifugal pump. A solenoid valve is fixedly mounted at the upper end of the volute centrifugal pump. An adapter pipe is fixedly mounted above the solenoid valve. A drain pipe is fixedly mounted at one end of the adapter pipe. The drive assembly also includes a support frame fixedly mounted above the tractor. A plunger pump is fixedly mounted above the support frame. A bend is fixedly mounted at the water inlet of the plunger pump. A hydraulic sensor is fixedly mounted at the top of the drain pipe.

[0009] The steering assembly, located above the front of the tractor unit, is used to adjust the direction of water discharge.

[0010] Preferably, the adjustment assembly includes a hydraulic arm fixedly installed above the tractor, a connecting frame fixedly installed on the left side of the boom of the hydraulic arm, a metal pipe fixedly installed at one end of the connecting frame, a connecting hose fixedly installed at the bottom end of the metal pipe, and a base fixedly installed at the bottom end of the hydraulic arm.

[0011] Preferably, there are three metal tubes, each with a length matching the length of a section of the hydraulic arm, and the metal tubes are connected by a rotating joint. Each connection point of the metal tube corresponds to a connection point of the hydraulic arm. The base has a 90-degree pipe cavity inside, and a connecting hose is also fixedly installed at the bottom of the base. The rear end of the connecting hose on the rear side of the metal tube is fixedly connected to a tee.

[0012] Preferably, there are two centrifugal pumps with volute casings, and each of them is equipped with a solenoid valve at its outlet. The upper end of the transfer pipe is connected to the bottom end of the drain pipe through one side of the solenoid valve, and the other side is fixedly connected to the inlet end of the plunger pump through a bend. The outlet end of the plunger pump is connected to the bottom end of the hydraulic sensor through the drain pipe.

[0013] Preferably, the steering assembly includes a limiting frame fixedly installed above the front of the tractor, a bearing fixedly installed inside the limiting frame, a transmission frame fixedly installed inside the bearing, a gear ring fixedly installed on the outer side of the transmission frame, and a stepper motor fixedly installed above the limiting frame.

Beneficial effects

[0015] This utility model provides a high-flow-rate drainage emergency vehicle with adjustable drainage pipes. Compared with the prior art, it has the following advantages:

[0016] (1) The adjustable high-flow drainage emergency vehicle uses a plunger pump and solenoid valves on the left and right sides above the transfer pipe to adjust the direction of the pipeline connection. When the left solenoid valve is closed and the right solenoid valve is open, the transfer pipe is connected to the water inlet of the plunger pump through a bend, so that the air inside the volute centrifugal pump and the lower pipeline can be discharged through the plunger pump in the initial stage of drainage. When the detection data of the hydraulic sensor is stable, the air inside the volute centrifugal pump is completely discharged and the volute is filled with water. Then the left solenoid valve is opened and the right solenoid valve is closed. The volute centrifugal pump is connected to the bottom of the drainage pipe through the transfer pipe. After the volute centrifugal pump is turned on, it can quickly drain water by taking advantage of the high flow rate of the volute centrifugal pump, avoiding the air inside the pipeline from affecting the drainage.

[0017] (2) The adjustable high-flow drainage emergency vehicle has two volute centrifugal pumps with solenoid valves. Both pumps have solenoid valves installed at their outlets. The inlet of the volute centrifugal pump is connected to the connecting hose at the rear end of the metal pipe via a tee. The solenoid valve above the volute centrifugal pump opens when the corresponding pump is turned on and closes when it is turned off. This method allows two volute centrifugal pumps to be turned on simultaneously in the high-demand section to deal with emergencies. Later, when the water level drops, only one volute centrifugal pump is used for drainage in non-emergency situations. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a high-flow-rate drainage emergency vehicle with adjustable drainage pipes, wherein a drainage mechanism 2 is installed above the tractor unit 1.

[0025] Adjustment component 21 is set above the tractor 1 to adjust the position of the water inlet end of the pipeline structure. Adjustment component 21 includes a hydraulic arm 211 fixedly installed above the tractor 1. A connecting frame 212 is fixedly installed on the left side of the upper arm of the hydraulic arm 211. A metal pipe 213 is fixedly installed at one end of the connecting frame 212. A connecting hose 214 is fixedly installed at the bottom end of the metal pipe 213. A base 215 is fixedly installed at the bottom end of the hydraulic arm 211. There are three metal pipes 213, and their lengths are respectively matched with the lengths of each arm section of the hydraulic arm 211. The metal pipes 213 are rotatably connected to each other. Each connection point of the metal pipe 213 corresponds to the connection point of the hydraulic arm 211. A 90-degree pipe cavity is provided inside the base 215. A connecting hose 214 is also fixedly installed at the bottom end of the base 215. The rear end of the connecting hose 214 on the rear side of the metal pipe 213 is fixedly connected to the tee 222.

[0026] Specifically, the tractor 1 can easily move the drainage mechanism 2 and adjust the position of the base 215 through the hydraulic arm 211 so that the bottom end of the connecting hose 214 under the base 215 can be below the liquid surface. Since a metal pipe 213 is fixedly connected to the upper arm of the hydraulic arm 211 and the metal pipes 213 form a rotatable connection, and the connection of the metal pipe 213 is in the same straight line as the bend of the hydraulic arm 211, when the angle between each arm section of the hydraulic arm 211 changes, it can drive the corresponding metal pipe 213 to rotate, so as to adjust the position of the base 215 while maintaining the connection between the metal pipes 213. The connecting hose 214 at the bottom of the base 215 has a certain deformation capacity to avoid contact with the bottom of the water body and damage during the adjustment of the position of the base 215.

[0027] The drive assembly 22 includes a volute centrifugal pump 221 fixedly mounted above the tractor 1. A three-way valve 222 is fixedly mounted at the inlet end of the volute centrifugal pump 221. A solenoid valve 223 is fixedly mounted at the upper end of the volute centrifugal pump 221. An adapter pipe 224 is fixedly mounted above the solenoid valve 223. A drain pipe 225 is fixedly mounted at one end of the adapter pipe 224. The drive assembly 22 also includes a support frame 226 fixedly mounted above the tractor 1. A plunger pump 2 is fixedly mounted above the support frame 226. 27. A bend 228 is fixedly installed at the water inlet of the plunger pump 227, and a hydraulic sensor 229 is fixedly installed at the top of the drain pipe 225. There are two volute centrifugal pumps 221, and both of them are equipped with solenoid valves 223 at their outlets. The upper end of the adapter pipe 224 is connected to the bottom end of the drain pipe 225 through one side of the solenoid valve 223, and the other side is fixedly connected to the water inlet of the plunger pump 227 through the bend 228. The water outlet of the plunger pump 227 is connected to the bottom end of the hydraulic sensor 229 through the drain pipe 225.

[0028] Specifically, the volute centrifugal pump 221 can pump water and deliver it to the upper transfer pipe 224. The solenoid valves 223 on the left and right sides of the transfer pipe 224 adjust the pipe connection direction. When the left solenoid valve 223 is closed and the right solenoid valve 223 is open, the transfer pipe 224 connects to the water inlet of the plunger pump 227 via the bend 228, facilitating the initial drainage by expelling air from the volute of the volute centrifugal pump 221 and the lower pipe via the plunger pump 227. The hydraulic sensor 229... When the detection data remains stable, the air inside the volute centrifugal pump 221 is completely expelled, and the volute is filled with water. Then, the left solenoid valve 223 opens and the right solenoid valve 223 closes. The volute centrifugal pump 221 is connected to the bottom end of the drain pipe 225 through the adapter pipe 224. After the volute centrifugal pump 221 is turned on, it can quickly drain water by taking advantage of its high flow rate. The water will enter the fixed pipe 239 through the adapter pipe 224 and the drain pipe 225 under the delivery of the volute centrifugal pump 221.

[0029] The steering assembly 23 is located above the front of the tractor 1 and is used to adjust the direction of water discharge. The steering assembly 23 includes a limiting frame 231 fixedly installed above the front of the tractor 1. A bearing 232 is fixedly installed inside the limiting frame 231. A transmission frame 233 is fixedly installed inside the bearing 232. A gear ring 234 is fixedly installed on the outside of the transmission frame 233. A stepper motor 235 is fixedly installed above the limiting frame 231. A gear 236 is fixedly installed on the outside of the shaft of the stepper motor 235. A guide tube 237 is fixedly installed at the center of the transmission frame 233. A rotary joint 238 is fixedly installed at the bottom end of the guide tube 237. A fixing tube 239 is fixedly installed at the bottom end of the rotary joint 238.

[0030] Specifically, the limiting frame 231 can limit the position of the transmission frame 233 through the bearing 232. Since the transmission frame 233 is rotatably connected to the limiting frame 231 through the bearing 232, when the stepper motor 235 starts, it will drive the gear 236 to rotate. The gear 236 will drive the gear ring 234 fixedly installed on the outside of the transmission frame 233 to rotate, so as to adjust the rotation angle of the transmission frame 233. Since the guide tube 237 is fixed to the center of the transmission frame 233 and its bottom end is rotatably connected to the fixed tube 239 through the rotary joint 238, the rotation of the transmission frame 233 will drive the guide tube 237 to rotate. The top end of the guide tube 237 has a 45-degree bend structure, which can increase the water flow head.

[0031] Specifically, the volute centrifugal pump 221 is model 200HW-7, the solenoid valve 223 is model DN20, the piston pump 227 is model A2FO, and the hydraulic sensor 229 is model PM1618. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] During operation, the pipe connection direction is adjusted by the solenoid valves 223 on the left and right sides above the adapter pipe 224. When the left solenoid valve 223 is closed and the right solenoid valve 223 is open, the adapter pipe 224 is connected to the water inlet of the plunger pump 227 through the bend 228, so that air inside the volute of the centrifugal pump 221 and the pipe below can be discharged through the plunger pump 227 in the initial drainage stage. When the detection data of the hydraulic sensor 229 remains stable, the air inside the centrifugal pump 221 is completely discharged and the volute is filled with water. Then the left solenoid valve 223 opens and the right solenoid valve 223 closes. The centrifugal pump 221 is connected to the bottom end of the drain pipe 225 through the adapter pipe 224. After starting the volute centrifugal pump 221, the high flow rate of the volute centrifugal pump 221 can quickly drain water, avoiding the influence of air inside the pipe on drainage. There are two volute centrifugal pumps 221, and both are equipped with solenoid valves 223 at their outlets. The inlet of the volute centrifugal pump 221 is connected to the connecting hose 214 at the rear end of the metal pipe 213 via a tee 222. The solenoid valve 223 above the volute centrifugal pump 221 opens when the corresponding volute centrifugal pump 221 is turned on and closes when it is turned off. This method allows two volute centrifugal pumps 221 to be turned on simultaneously in the early stage when the drainage demand is high in order to deal with emergency situations. Later, when the water level drops, only one volute centrifugal pump 221 is used for drainage in non-emergency situations.
