Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to a new type of internal combustion engine flood control drainage device. Background Art

[0002] The mobile drainage equipment driven by a diesel engine or a gasoline engine (also known as an internal combustion engine flood control drainage device), due to the lack of need for power supply and convenient for mobile use, is widely used in the field of emergency drainage (such as draining the accumulated water in the underground garage of a community).

[0003] With the progress of industrial technology, the technology of the flood control drainage device driven by an internal combustion engine has also developed. The authorized patent with the patent number "201510105218.8" and the patent name "An internal combustion engine water pump" in China records that "during operation, the end face of the graphite bearing fits and slides on the stepped smooth plane ring to seal the rotation gap between the water pump housing and the water pump shaft to play a water sealing role. This water pump can be used on internal combustion engines such as automobiles". As can be seen from the above patent, although it achieves its stated invention purpose, due to structural limitations, like other existing devices in this field, there are still some specific technical problems, which are specifically reflected as follows. When the device is applied to flood control drainage, there is no suitable filtering device for the water inlet pipe of the volute of the supporting self-priming water pump. In this way, after sundries in the water are sucked into the volute with the water flow, there is a risk of blocking the pipeline and damaging the blades in the volute. In extreme cases, it is also possible to cause the blades to be stuck in the volute and the load of the internal combustion engine to be too large and damaged. In summary, it is very necessary to provide an internal combustion engine flood control drainage device that can effectively filter impurities in the water. Summary of the Utility Model

[0004] In order to overcome the disadvantages of the existing internal combustion engine flood control drainage equipment due to structural limitations as described in the background, the utility model provides an internal combustion engine flood control drainage equipment body. Under the joint action of relevant mechanisms, it can effectively filter the sundries in the water entering the volute through the filter box, and can prompt the staff to switch when a corresponding section of the filter box is blocked. The staff can control and switch another section of the filter box to filter the water entering the volute through a simple power switch control method, ensuring the continuous use of the equipment, improving work efficiency, and after the work is completed, the staff can conveniently backwash the filter holes clean.

The internal combustion engine flood control and drainage equipment body 1 is installed at the upper end of a hand-pushed mobile trolley 2 (with wheels at the lower end to facilitate the manual transfer of the position by the staff) through bolts, and also has a filtering mechanism 3 and a prompting mechanism; the filtering mechanism includes a small waterproof electric push rod M1 (both the cylinder body and the push column are made of rust-proof metal materials, and the wires connected to it are led out through the opening at the upper end of the filter shell, and the opening is sealed with sealant), a rectangular hollow filter shell 31 (made of rust-proof material), a filter screen box 32 (made of rust-proof material), a sealing plate 39 (made of rust-proof material). The right end of the filter shell 31 is an open structure, and a fixing plate 38 is welded to the outer end. There are multiple fixing screw holes around the fixing plate 38, and multiple fixing holes around the sealing plate 39. A plurality of bolts are screwed into the multiple screw holes of the fixing plate 38 through the multiple fixing holes around the sealing plate to seal and install the sealing plate and the right end of the filter shell 31 together. There is an opening at the left end of the filter shell 31 and at the lower-middle position outside the sealing plate 39 respectively. A drain pipe 33 and a water suction pipe 34 that communicate with their interiors are welded to the outside of the two openings respectively. A circular hollow support seat 35 (made of rust-proof material) is welded to the inside of the two openings respectively. The filter screen box 32 is a rectangular hollow structure, and there are multiple filter holes 321 at the left and right ends of the filter screen box 32 (every two filter holes at the left and right ends are horizontally penetrated by a filter pipe); the upper end of the cylinder body of the electric push rod M1 is vertically installed at the upper end inside the filter shell 31 through bolts, the lower end of the push column of the electric push rod M1 and the outer middle part of the upper end of the filter screen box 32 are bolted together, and the lower end of the filter screen box 32 is located between the two support seats 35; a drain pipe A36 (made of rust-proof material) that communicates with its interior is welded to the middle part of the lower end of the filter shell 31. The lower end of the drain pipe A36 has an internal thread, and a plug 361 (made of rust-proof material) is installed by screwing into the lower end of the drain pipe through the internal thread; the outer side of the left end of the drain pipe 33 has an external thread, and the left end of the drain pipe 33 is connected to the volute water inlet pipe (with an external thread) of the self-priming pump 101 of the internal combustion engine flood control and drainage equipment body through a pipe joint. The right side of the water suction pipe 34 is hermetically sleeved with a water suction rubber hose with a certain strength ( Figure 1It is not shown in the figure. The lower end of the water suction pipe is located in the water of the drainage area. When not in use usually, it is separated from the water suction pipe 34 and rolled into a circle for convenient storage. The prompting mechanism includes a pressure probe D1 and a buzzer B1. There is a threaded seat in the middle of the upper end of the drainage pipe 33. The intake pipe of the pressure probe D1 is screwed into the internal thread of the threaded seat through an external thread and installed on the drainage pipe 33. The power switches S1 and S3 (S2), and the buzzer B1 are installed in the component box 102 of the internal combustion engine flood control drainage equipment body. The power input terminals 1 and 2 of the power switch S3, the power input terminal of the pressure probe D1 (a power switch AS2 is connected in series between it and the positive pole of the storage battery G1), and the two poles of the starting storage battery G1 of the internal combustion engine flood control drainage equipment body are connected in series through the main power switch S1 and are respectively connected through wires. The power output terminals 3, 4, 5, and 6 of the power switch S3 and the positive and negative and negative and positive power input terminals of the electric push rod M1 are respectively connected through wires. The handles of the power switches S1 and S3 and the power switch AS2 are located outside the three openings at the front end of the component box 102. The buzzer B1 is an active high-decibel alarm of model HND-4216. The electric push rod M1 is a finished product of a small reciprocating electric telescopic rod with a power of 10W, and there are limit switches at the upper and lower ends of the cylinder body respectively. When the push rod moves up or down to the stop point, the motor of the electric push rod will lose power, but it does not affect the power supply of the inverting input power supply. The pressure probe D1 is a mechanically adjustable electric contact pressure switch of model SY-S60 (normally closed structure).

[0018] Figure 1 、 2 As shown in Figures 3 and 4, an annular hollow sealing rubber ring 37 is adhesively bonded to the inner sides of the two support seats respectively. The left and right side ends of the filter box 32 are in sealed sliding contact with the inner sides of the two sealing rubber rings 37 respectively. The height of the filter box 32 is more than twice the inner diameter of the two support seats 35, and the outer diameter of the filter box 32 is larger than the inner diameters of the support seats 35 and the sealing rubber ring 37. In the prompting mechanism, the power output terminal of the pressure probe D1, the negative pole of the storage battery G1, and the two power input ends of the buzzer B are respectively connected through wires. The pressure probe D1 is a normally closed adjustable electric contact pressure switch. When the push rod of the electric push rod M1 is at the upper dead center, a section of the lower end of the filter box 32 is located between the inner sides of the two support seats 35 and the sealing rubber ring 37. When the push rod of the electric push rod M1 is at the lower dead center, a section of the upper end of the filter box 32 is located between the inner sides of the two support seats 35 and the sealing rubber ring 37.

[0019] Figure 1 、 2As shown in Figures 3 and 4, the main body 1 of the internal combustion engine flood control drainage equipment based on the working mode of the internal combustion engine-driven self-priming pump has a push-type mobile trolley 2, which can be conveniently transferred to the required position for drainage operations; specifically, the staff moves the equipment to the corresponding position, and a pumping rubber hose with a certain strength is hermetically sleeved on the right side of the water suction pipe 34. The lower end of the water suction pipe is located in the water in the drainage area. After pressing the start power switch of the main body 1 of the internal combustion engine flood control drainage equipment, the storage battery G1 outputs power to the start motor of the internal combustion engine, and the start motor starts the internal combustion engine. The power output shaft of the internal combustion engine drives the rotating shaft of the self-priming pump, and the rotating shaft drives the blades in the volute to rotate. Thus, the self-priming pump pumps the water at a low position and then discharges it to other areas through the drain pipe (connected with a hose, etc.) of the self-priming pump. The above is the existing mature technology, and this application will not elaborate on the above specific working principle, nor will it claim any protection for the above technical solution. After turning on the power switch AS2 (including turning on S1), the pressure probe D1 is powered on and works (turn on S2 10 seconds after pumping to prevent false alarms due to too low water pressure detected by the initial pressure probe D1). In this new type, when the blades in the volute of the self-priming pump driven by the internal combustion engine rotate to pump water, the water can be filtered by the filter box 32 before entering the volute (entering the right end of the filter box 32 through the water suction pipe 34, and then flowing out from the left end of the filter box 32 and entering the drain pipe, and then entering the volute). Due to the function of the filter holes 321 of the filter box, it effectively prevents sundries from entering the volute and causing the blades to get stuck or damaged, and reduces the probability of the internal combustion engine being damaged due to excessive load. In actual situations, when the self-priming pump is pumping water normally and the water enters the drain pipe through the volute, due to the relatively high water volume and water pressure entering, the internal contacts of the pressure probe D1 will not close (open circuit). In this way, the buzzer B1 will not be powered on and sound, indicating that no blockage has occurred in the lower section of the corresponding filter box 32; when the lower section of the filter box 32 is completely blocked or mostly blocked, due to the relatively low water volume and water pressure entering, the internal contacts of the pressure probe D1 will close. In this way, the buzzer B1 will be powered on and sound, indicating that a blockage has occurred in the lower section of the corresponding filter box 32. After the staff hears the buzzer B1 sound, they can move the handle of the power switch S1 to the left. Thus, the 1st and 2nd pins and the 3rd and 4th pins of the power switch S1 are respectively connected. In this way, the positive and negative power input terminals of the electric push rod M1 will be powered on, and its push rod moves to the lower dead center and stops (turn off the power switch after about 5 seconds). At this moment, the lower section of the filter box is located outside the lower ends of the inner sides of the two support seats, and the upper section of the filter box is located between the inner sides of the two support seats. The filter holes in the upper section of the filter box are not blocked, and the self-priming pump can normally suck and discharge water again, ensuring continuous drainage work without the self-priming pump stopping and improving work efficiency.After normal shutdown, the staff can separate the drain pipe from the volute, open the screw plug 361, drain the accumulated water that leaks in under extreme conditions inside, and then connect the drain pipe at the left end of the filter housing and the tap water pipe through a hose. High-pressure tap water enters from the drain pipe and flushes the filter holes of the filter screen box in the reverse direction. After flushing, the waste water flows out from the right end of the filter screen box and is discharged outward through the water extraction pipe 34. In actual situations, the staff can move the power switch S1 to the left or right. In this way, the 1st and 2nd pins, or the 3rd and 4th pins, or the 5th and 6th pins of the power switch S1 are connected respectively. In this way, the positive and negative or negative and positive power input terminals of the electric push rod M1 will be powered on. After the positive and negative power input terminals of the electric push rod M1 are powered on, its push rod moves to the lower dead center and stops. A section of the lower end of the filter screen box is located outside the lower ends inside the two support seats, and a section of the upper end of the filter screen box is located between the two support seats inside. At this moment, the upper section of the filter screen box is flushed in the reverse direction; after the negative and positive power input terminals of the electric push rod M1 are powered on, its push rod moves to the upper dead center and stops. A section of the upper end of the filter screen box is located outside the upper ends inside the two support seats, and a section of the lower end of the filter screen box is located between the two support seats inside. At this moment, the lower section of the filter screen box is flushed in the reverse direction. After the cleaning is completed, it is ready for the next use (in extreme cases, when the reverse flushing cannot effectively remove the debris in the filter holes, the staff can remove the sealing plate, electric push rod, filter screen box, etc. respectively and clean the debris in the filter holes manually with iron wire, etc.).
