Description

Technical Field

[0001] The present invention relates to the technical field of emergency pumps, and specifically to a self-cleaning emergency drainage and rescue pump. Background Art

[0002] In some areas such as urban streets, underground garages, and subway stations where water accumulates due to heavy rain. Especially at the scene of natural disasters such as floods and heavy rains in a complex and changeable environment. Traditional emergency drainage pumps, due to the limitation that usually only a single filter screen is set at the water inlet, have the following deficiencies in practical applications:

[0003] First, it is easily blocked by impurities in the water (such as sediment, leaves, plastic bags, etc.) on the filter screen at the water inlet, resulting in a reduction in the normal drainage efficiency; and once it is blocked, it not only increases the cleaning burden on the staff, but may also require the machine to be shut down for cleaning in severe cases, which undoubtedly prolongs the rescue time and thus affects the rescue effect.

[0004] Second, when used in a harsh environment, due to the difficulty of the static filter screen in providing effective protection, the impeller on the rescue pump is easily impacted by hard objects such as stones, increasing the risk of damage.

[0005] In addition, an invention patent of an emergency drainage and rescue pump with a self-cleaning function disclosed on the Chinese Patent Network, with an application date of April 12, 2021 and an authorization announcement number of CN214660917U. This device includes a submersible pump and support wheels, and also includes a filtering device. The filtering device includes a tank body and a cover body. Multiple moving wheels are installed at the bottom of the tank body, a water inlet pipe is provided on one side, and a water outlet pipe is provided on the other side. A plurality of support angle blocks are evenly arranged on the inner wall of the cavity of the tank body, and a screen assembly is placed on the support angle blocks. The screen assembly is located below the water outlet end of the water inlet pipe. This device prevents foreign objects from entering the pump body through the water inlet by setting the filtering device and multiple filter screens to ensure the safety of the pump body; however, this device still has difficulty in solving the problem that the filter screen is easily blocked during use with multiple statically set filter screens, resulting in unstable drainage and low efficiency, and will increase the energy consumption to a certain extent.

[0027] Embodiment: An automatically cleaning type emergency drainage and rescue pump provided by the present invention, as Figures 1 to 8 shown, includes an emergency pump 1, a water inlet cover 2, a drain pipe 3, an outer partition cleaning component and an inner partition protection component. The output end of the emergency pump 1 is connected with a frustum-shaped water inlet cover 2 with a hollow structure. The end of the water inlet cover 2 is connected with a drain pipe 3, and the outer end of the drain pipe 3 is used for externally connecting a water pipe for drainage; and the output shaft and the impeller of the emergency pump 1 extend into the drain pipe 3. The outer partition cleaning component is rotatably sleeved between the housing of the emergency pump 1 and the drain pipe 3 for actively cleaning the impurities outside the water inlet cover 2. The outer partition cleaning component includes symmetrically arranged detachable partition covers 4, limiting rings 45 and a driving mechanism. The partition cover 4 is fixed to the outer wall of the drain pipe 3 through the limiting ring 45 and is driven to rotate by the driving mechanism. The inner partition protection component includes a positioning ring 6, a protective cover 60 and an elastic part 61 slidably installed inside the drain pipe 3. The protective cover 60 is connected to the positioning ring 6, and the protective cover 60 wraps around the periphery of the output shaft and the impeller of the emergency pump 1. The protective cover 60 is designed as a hollow inverted conical structure, and the surface aperture thereof is smaller than the aperture of the water inlet cover 2, thereby being beneficial to secondarily filtering the impact force of hard objects such as stones on the impeller of the present emergency pump 1 and achieving the purpose of protecting the impeller of the present emergency pump 1. An elastic part 61 is connected between the side port of the positioning ring 6 and the inner side of the drain pipe 3. The elastic part 61 is a compression spring for resetting the positioning ring 6 and the protective cover 60 connected thereto. Through the dual dynamic cooperation of the partition cover 4 capable of rotating circumferentially around the periphery of the water inlet cover 2 and the protective cover 60 capable of reciprocating axially inside the water inlet cover 2, the purpose of automatically cleaning the present emergency pump 1 can be effectively achieved, and thus it is beneficial to be applicable to use in complex environments.

[0028] Furthermore, asFigures 3 to 8 As shown, the outer partition cleaning assembly further includes an arc-shaped guide rail 40, a fixing member 42 and a connecting sleeve 51. The outer partition cleaning assembly further includes an arc-shaped guide rail 40, a fixing member 42 and a connecting sleeve 51. The arc-shaped guide rails 40 are symmetrically arranged on the two partition covers 4. The two partition covers 4 are snap-fitted with the limit rings 45 through the card slots 41 on the arc-shaped guide rails 40 and locked by the fixing member 42. Among them, the fixing member 42 is a bolt and a nut. By using the bolt and the nut, the two partition covers 4 can be assembled and installed on the limit ring 45; a groove 30 is provided on the outer wall of the drain pipe 3. The connecting sleeve 51 is installed in the groove 30 through a bearing, and the limit ring 45 is fixed on the connecting sleeve 51, which can realize flexible installation and disassembly and is convenient to use.

[0029] Further, as Figures 6 to 8 shown, the inner partition protection assembly further includes a vibration assembly. The vibration assembly includes a wave ring 7, a push arm 70 and a roller 71 connected to the connecting sleeve 51. The push arms 70 are arranged at intervals on the side of the positioning ring 6. A roller 71 is arranged on the side of the push arm 70 close to the wave ring 7, and the roller 71 abuts against the edge of the ring opening of the wave ring 7. A guide groove 20 for the directional sliding of the push arm 70 is provided inside the water inlet cover 2. When the partition cover 4 rotates, the positioning ring 6 and the protective cover 60 can move back and forth along the axial direction of the drain pipe 3, so as to achieve the purpose of vibrating the protective cover 60, which is beneficial to preventing hard objects such as stones from impacting the impeller of the emergency rescue pump 1, so that the impeller of the emergency rescue pump 1 can operate stably for a long time.

[0030] Further, as Figure 1 、 Figure 5 、 Figure 6 and Figure 7 shown, the driving mechanism includes a driving motor 5, a gear 50 and a gear ring 52. The driving motor 5 is installed on the outer wall of the drain pipe 3. A gear 50 is sleeved on the output shaft of the driving motor 5. The gear ring 52 is fixedly sleeved on the connecting sleeve 51, and the gear 50 meshes with the gear ring 52 to drive the gear ring 52 and the connecting sleeve 51 to rotate synchronously; the structure is simple and convenient to operate and control.

[0031] Further, as Figure 4 and Figure 5 shown, it further includes a positioning structure. The positioning structure is mainly composed of a positioning column 43 and a positioning hole 44 that are inserted and matched with each other. The positioning column 43 is installed on the side of one of the partition covers 4, and a positioning hole 44 corresponding to the positioning column 43 is provided on the side of the other partition cover 4, and the positioning column 43 can be inserted into the positioning hole 44; it is convenient to accurately assemble and install the two partition covers 4, and can also improve the structural stability of the partition cover 4 after combination.

[0032] In addition, as Figure 1 and Figure 2As shown in the figure, it further includes a support frame 9. Fixing rings 8 are respectively arranged on the outer walls of the emergency pump 1 and the drain pipe 3. The support frame 9 is symmetrically arranged on the fixing ring 8, and the support frame 9 is located outside the two partition covers 4. Through the supporting and protecting function of the support frame 9, the water inlet cover 2 can be in a suspended state, which is convenient for the convenient installation and anti-extrusion of the partition cover 4. It also includes lifting lugs 10. The lifting lugs 10 are respectively arranged on the horizontal axes of the outer walls of the emergency pump 1 and the drain pipe 3. During use, the emergency pump 1 as a whole can be hoisted and moved by tying a lifting rope to the lifting lug 10, which is convenient to use.

[0033] After connecting the water inlet pipe to the water outlet end of the drain pipe 3, the emergency pump 1 can be started to work. The suction force generated when the impeller of the emergency pump 1 rotates can suck water from the water inlet cover 2 and discharge it through the drain pipe 3 and the water inlet pipe. When it is necessary to clean the impurities attached to the outer side of the water inlet cover 2, only need to control the driving motor 5 to work. Through the transmission of the gear 50 and the gear ring 52, the connecting sleeve 51 and the limiting ring 45 are driven to rotate synchronously. The partition cover 4 rotates while blocking the impurities located outside the water inlet cover 2. And through the design that the outer side of the partition cover 4 protrudes and extends outwards, it can push aside the surrounding impurities while rotating, avoiding the impurities directly attaching to the outside of the partition cover 4 and causing blockage. It is beneficial to realize the self-cleaning function, thereby effectively improving the drainage efficiency of the emergency pump 1 and achieving the energy-saving effect to a certain extent. And this design can also significantly improve the efficiency of emergency rescue, avoiding the problem that the drainage efficiency is reduced due to the blockage of the partition cover 4, and further increasing the energy consumption.

[0034] In addition, while the connecting sleeve 51 rotates, it can also drive the wave ring 7 to rotate synchronously. Through the cooperation of the push arm 70, the roller 71 and the elastic member 61, the positioning ring 6 and the protective cover 60 can axially reciprocate along the water inlet cover 2. Through this vibration filtering method, not only can effectively prevent impurities from directly attaching to the protective cover 60, but also can effectively avoid the impact damage of the impeller of the emergency pump 1 caused by the inhalation of hard objects such as stones. In this way, it is beneficial to further improve the self-cleaning efficiency of the emergency pump 1, so as to minimize the drainage time within a certain range, and then achieve the purpose of saving energy consumption.

[0035] When the emergency pump 1 is used up, turn off the emergency pump 1 and the driving motor 5, and the partition cover 4 can be disassembled to facilitate the maintenance of the inside of the emergency pump 1.

[0036] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
