Large-flow drainage rescue vehicle capable of avoiding water inlet blockage

Abstract

This utility model discloses a high-flow-rate drainage emergency vehicle that avoids water inlet blockage, relating to the field of emergency vehicle technology. The utility model includes a main body of the emergency vehicle, with an anti-blocking mechanism on one side to prevent blockage at the water inlet. When the main body of the emergency vehicle cannot reach the pumping area, the suspended ball and filter cover are separated from the fixed plate and placed on the water surface. The counterweight of the mounting plate and the buoyancy of the suspended ball work together to ensure the filter cover is stably positioned in a suitable position in the water. The waterproof motor is activated to drive the propulsion fan blades to rotate, causing some of the filtered water to be sprayed downwards through the lower casing. On one hand, the reaction force generated by the sprayed water increases the overall buoyancy of the suspension assembly, preventing the filter cover from sinking and getting stuck with mud and impurities due to excessive pumping force. On the other hand, the high-speed sprayed water forcefully washes the outer wall of the filter cover, effectively removing attached algae, debris, etc., maintaining the permeability of the filter cover and preventing the impact of debris on pumping efficiency.

Description

Technical Field

[0001] This utility model relates to the field of emergency rescue vehicle technology, specifically a high-flow-rate drainage emergency rescue vehicle that avoids water ingress and blockage. Background Technology

[0002] A drainage and emergency rescue vehicle is a special vehicle designed for emergency drainage and rescue operations in urban flooding, underground water accumulation, and natural disasters (such as rainstorms and floods). It is equipped with a high-flow water pump (capacity of hundreds to thousands of cubic meters per hour) for rapid pumping out accumulated water.

[0003] Referring to the patent document: Patent Publication No. CN114670939A, Patent Publication Date 2022-06-28, a tracked high-flow-rate drainage emergency vehicle is disclosed, including tracks, a base plate installed on the top of the tracks, a driver's cab installed on the left side of the top of the base plate, a water storage tank installed on the right side of the top of the base plate, a water suction pipe penetrating the front end of one side of the water storage tank, a high-pressure water pump mounted on the top of the water suction pipe, and a top plate installed at the bottom of the fixed plate. This tracked high-flow-rate drainage emergency vehicle is equipped with a metal filter screen, a limiting seat, a top plate, and a fixed plate. In use, the high-pressure water pump is started through the control box to pump water into the water storage tank. After entering the water storage tank, the metal filter screen filters impurities in the water, preventing blockages caused by large diameter impurities in the water. After a period of use, the bolts at the top plate are rotated to remove the filter screen, clean it, and then the metal filter screen is reinstalled for continued use. This solves the problem of large impurities in the water easily clogging the pipes.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Currently, drainage and emergency rescue vehicles on the market often have filter covers installed at the ends of the pipes to prevent blockages during actual operations. This is to prevent garbage from entering the pipes and causing blockages. However, during transportation, the pipes and filter covers are often placed underwater together, causing the filter cover to touch the bottom. The bottom of the water contains a lot of mud and sand, which can easily block the side of the filter cover that is in contact with the ground, resulting in reduced pumping efficiency. At the same time, under the suction of the pump, garbage (such as garbage bags) is often directly adsorbed onto the surface of the filter cover, causing the filter holes on the filter cover to become blocked, thus affecting the efficiency of drainage and emergency rescue operations.

[0006] Therefore, this utility model provides a high-flow-rate drainage emergency vehicle that avoids water ingress blockage. Utility Model Content

[0007] To address the problems of existing systems where filter covers are installed at the ends of the inlet pipes, but these covers often directly touch the bottom, making them prone to clogging by sediment and debris, and causing reduced pumping efficiency due to suction, this invention aims to provide a high-flow-rate drainage emergency vehicle that avoids inlet blockage.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-flow-rate drainage emergency vehicle that avoids water inlet blockage, comprising a vehicle body, wherein an anti-blocking mechanism is provided on one side of the vehicle body to prevent blockage at the water inlet end, the anti-blocking mechanism comprising:

[0009] The suspension assembly includes a fixed platform fixedly installed on one side of the main body of the rescue vehicle. The lower part of the fixed platform has two symmetrically distributed mounting plates. A suspension ball is fixedly installed in the middle of the two mounting plates. A filter cover is fixedly installed at the bottom of the two suspension balls. Several evenly distributed fixing frames are fixedly installed on the outer side of the two filter covers. An upper shell is fixedly installed on one side of the fixing frames. A propulsion fan blade is rotatably installed in the middle of the upper shell. A waterproof motor is fixedly installed on one side of the upper shell. The top of the propulsion fan blade is fixedly installed at the drive end of the waterproof motor. A middle shell is fixedly installed in the lower part of the upper shell. A lower shell is fixedly installed at the bottom of the middle shell. The middle of the lower shell is fixedly installed in the middle of the fixing frame.

[0010] An adjustment component, located in the middle of the fixed platform, is used to adjust the height of the filter cover.

[0011] Preferably, a cylinder is fixedly installed at the top center of the fixed platform, and a fixed plate is provided at the bottom of the fixed platform. The bottom surfaces of the two mounting plates are in contact with the top surface of the fixed plate, and the top center of the fixed plate is fixedly installed at the driving end of the cylinder.

[0012] Preferably, an installation pipe is fixedly installed at the top center of the filter cover, and two conveying holes that cooperate with the installation pipe are opened at the center of the fixed platform.

[0013] Preferably, each of the two mounting plates has two diagonally distributed bolts slidably extending through its upper part, and nuts are threaded onto the lower part of each bolt.

[0014] Preferably, the upper part of the fixing plate has two sets of positioning holes, and the lower part of the mounting plate is slidably engaged in the middle of the positioning holes.

[0015] Preferably, four evenly distributed telescopic rods are fixedly installed on the upper part of the fixed platform, and the bottom ends of the four telescopic rods are all fixedly installed on the top of the fixed plate. Beneficial effects

[0016] This invention provides a high-flow-rate drainage emergency vehicle that avoids water ingress blockage. Compared with the prior art, it has the following advantages:

[0017] 1. When the main body of the emergency vehicle cannot reach the pumping area, the suspended ball and filter cover are separated from the fixed plate and placed on the water surface. The counterweight of the mounting plate and the buoyancy of the suspended ball work together to ensure that the filter cover is stably positioned in a suitable position in the water. The waterproof motor is started to drive the propulsion fan blades to rotate, so that some of the filtered water is sprayed downward through the lower shell. On the one hand, the reaction force generated by the sprayed water increases the overall buoyancy of the suspension component, preventing the filter cover from sinking to the bottom and getting contaminated with mud and impurities due to excessive pumping force. On the other hand, the high-speed sprayed water has a strong impact force to wash the outer wall of the filter cover, which can effectively remove attached algae, debris, etc., keep the filter cover transparent, and prevent external debris from affecting the pumping efficiency.

[0018] 2. When the main body of the emergency vehicle arrives at the pumping location, the operator issues an instruction through the control system, and the cylinder drives the fixed plate to move the filter cover up and down, so that the filter cover accurately enters the appropriate working depth, avoiding the filter cover from being placed directly on the bottom, which would easily cause the filter cover to become clogged, and enabling the drainage emergency vehicle to quickly adapt to drainage operation environments of different depths.

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a high-flow-rate drainage emergency vehicle that avoids water inlet blockage, including an emergency vehicle body 1, with an anti-blocking mechanism 2 on one side of the emergency vehicle body 1 to prevent blockage at the water inlet end. The anti-blocking mechanism 2 includes:

[0027] The suspension assembly 21 includes a fixed platform 211 fixedly installed on one side of the main body 1 of the rescue vehicle. The lower part of the fixed platform 211 has two symmetrically distributed mounting plates 212. The two mounting plates 212 serve both as mounting and counterweight, and their weight is less than the buoyancy of the suspension balls 213, preventing the filter covers 214 from sinking to the bottom. Suspension balls 213 are fixedly installed in the middle of each of the two mounting plates 212, and filter covers 214 are fixedly installed at the bottom of each of the two suspension balls 213. The suspension balls 213 are made of lightweight and high-strength hollow composite material, filled with a special buoyancy medium, which can generate sufficient buoyancy in water. Several evenly distributed mounting brackets 215 are fixedly installed on the outer sides of each of the two filter covers 214. One side of each of the upper housings 216 is fixedly installed. Propulsion fan blades 217 are rotatably installed in the middle of each of the upper housings 216. A waterproof motor 2171 is fixedly installed on one side of the upper part of each of the upper housings 216. The waterproof motor 2171 is an IP68 deep-water motor, model SF86H48V-155, which can operate stably underwater for a long time and meet the operational needs of the drainage and rescue vehicle in complex waters. The top of each of the propulsion fan blades 217 is fixedly installed on the drive end of the waterproof motor 2171. A middle housing 2161 is fixedly installed on the lower part of each of the upper housings 216. A lower housing 2162 is fixedly installed on the bottom of each of the middle housings 2161. The middle part of the lower housing 2162 is fixedly installed in the middle of the fixed frame 215.

[0028] Adjustment component 22 is located in the middle of fixed platform 211 and is used to adjust the height of filter cover 214.

[0029] A cylinder 221 is fixedly installed at the top center of the fixed platform 211. The cylinder 221 is a Festo all-stainless steel waterproof cylinder, which can adapt to driving operations in complex environments. It is also connected to the control system of the main body 1 of the rescue vehicle, and the start and stop of the cylinder 221 are controlled by the control system. A fixed plate 222 is provided at the bottom of the fixed platform 211. The bottom surfaces of the two mounting plates 212 are in contact with the top surface of the fixed plate 222. The top center of the fixed plate 222 is fixedly installed at the driving end of the cylinder 221, which can quickly adjust the height of the filter cover 214 to adapt to different depth environments.

[0030] An installation pipe 2141 is fixedly installed at the top center of the filter cover 214. Two conveying holes 2111 are opened in the middle of the fixed platform 211 to cooperate with the installation pipe 2141. By opening the conveying holes 2111, the conveying pipe of the rescue vehicle body 1 can be connected to the installation pipe 2141 through the conveying holes 2111.

[0031] Two bolts 218 are slidably inserted through the upper part of each of the two mounting plates 212. Nuts 2181 are threaded onto the lower part of each bolt 218. The bolts 218 and nuts 2181 are made of high-strength stainless steel, which has good rust resistance, is easy to disassemble during subsequent use, and ensures a firm and reliable connection.

[0032] The upper part of the fixing plate 222 is provided with two sets of positioning holes 219. The lower part of the mounting plate 212 is slidably locked in the middle of the positioning holes 219. The design of the positioning holes 219 can not only accurately position the mounting plate 212, making it convenient to pass the bolts 218 through the through holes on the fixing plate 222 and tighten the nuts 2181 on the lower part to fix the mounting plate 212, but also restrict the movement of the mounting plate 212 to a certain extent, further improving the stability of the entire system.

[0033] Four evenly distributed telescopic rods 223 are fixedly installed on the upper part of the fixed platform 211. The bottom ends of the four telescopic rods 223 are all fixedly installed on the top of the fixed plate 222. By setting the telescopic rods 223, the fixed platform 211 can be limited, ensuring that the vertical movement of the fixed platform 211 is more stable.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when the main body 1 of the emergency vehicle can reach the water pumping location, the fixed plate 222 can be moved downward by starting the cylinder 221, so that the filter cover 214 is completely submerged in the water. By connecting the installation pipe 2141 with the delivery pipe of the main body 1 of the emergency vehicle, water can be pumped out through the filter cover 214 by the water pumping system of the main body 1 of the emergency vehicle.

[0036] When the main body 1 of the emergency vehicle cannot reach the pumping area, the nut 2181 can be unscrewed to release the bolts 218 and nut 2181 from the mounting plate 212, thereby allowing the suspension ball 213 to be removed from the fixing plate 222. The suspension ball 213 can then be placed in the pumping area. With the counterweight of the mounting plate 212, the filter cover 214 can be fully submerged in the water, enabling pumping operations. At the same time, the waterproof motor 2171 can be started, which drives the propulsion fan blade 217 to rotate, allowing some of the water that has entered the filter cover 214 to be sprayed downwards through the lower housing 2162. This increases the buoyancy of the suspension component 21 as a whole, preventing the filter cover 214 from sinking to the bottom due to excessive pumping force, which would easily cause it to be contaminated with mud and impurities from the bottom. The water spraying also cleans the outer wall of the filter cover 214, preventing debris from adhering to the outer surface of the filter cover 214 and affecting the pumping effect.
