Description

TECHNICAL FIELD

[0001] The application relates to the technical field of emergency rescue pumps, and particularly relates to a self-cleaning emergency drainage rescue pump. BACKGROUND

[0002] In some urban streets, underground garages, subway stations and the like, waterlogging is caused by heavy rain. In particular, in complex and changeable environments, such as flood and heavy rain disaster sites. Due to the limitation that only a single filter screen is arranged at the water inlet of the traditional emergency drainage pump, the following disadvantages exist in actual application:

[0003] 1. The impurities (such as silt, leaves, plastic bags and the like) in the water are easily blocked on the filter screen at the water inlet, which reduces the normal drainage efficiency; and once the blockage occurs, the cleaning burden of the staff is increased, and in severe cases, the pump needs to be stopped for cleaning, which undoubtedly prolongs the rescue time and affects the rescue effect.

[0004] 2. When used in harsh environments, the filter screen arranged statically cannot effectively provide protection, so that the impeller on the emergency rescue pump is easily impacted by hard objects such as stones, thereby increasing the risk of damage.

[0005] In addition, an invention patent of an emergency drainage rescue pump with a cleaning function disclosed on the Chinese patent network has an application date of April 12, 2021, and an authorized announcement number CN214660917U. The device comprises a submersible pump and a supporting wheel, and further comprises a filter device. The filter device comprises a tank body and a cover body. The tank body is provided with a plurality of moving wheels at the bottom, an inlet pipe at one side and an outlet pipe at the other side. A plurality of support angle blocks are uniformly arranged on the inner wall of the cavity of the tank body. A screen assembly is placed on the support angle blocks and located below the outlet end of the inlet pipe. The device prevents foreign matters from entering the pump body through the inlet by means of the filter device and the multiple filter screens, thereby ensuring the safety of the pump body. However, the device still cannot solve the problem of easy blockage of the filter screen during use, which leads to unstable drainage and low efficiency, and increases the energy consumption to a certain extent.

[0010] As a further improvement of the above technical scheme, the protective cover is designed in a hollow inverted conical structure, the surface aperture of the protective cover being smaller than the aperture of the water inlet cover.

[0011] As a further improvement of the above technical scheme, the inner barrier protection assembly further comprises a vibration assembly, the vibration assembly comprising a wave ring connected to the connecting sleeve, a push arm and a roller, the push arm being arranged at intervals on the side edge of the positioning ring, the roller being arranged on the push arm close to the wave ring, the ring opening edge of the wave ring abutting against the roller, and a guide groove being formed in the inner side of the water inlet cover for directional sliding of the push arm, the positioning ring and the protective cover being able to vibrate axially along the drainage pipe when the barrier cover rotates.

[0015] As further improvement of the above technical scheme, the lifting lug is further included, and the lifting lug is arranged on the horizontal axis of the rescue pump and the outer wall of the drain pipe.

[0016] The rescue pump has the advantages that: the outer barrier cleaning assembly is arranged, so that the barrier cover can effectively block and push away impurities during rotation, so as to avoid blockage during drainage, and the function of automatically cleaning impurities can be realized; in addition, through cooperation of the vibration assembly and the inner barrier protection assembly, impurities can be further prevented from adhering to the protection cover, and the impeller can be protected from impact damage of hard objects such as stones; in this way, through double dynamic cooperation of the inner and outer self-cleaning structures, the drainage time can be maximally reduced, so as to be beneficial to improving the overall drainage efficiency of the rescue pump, and achieving the purpose of energy saving to a certain extent.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example: The present invention provides a self-cleaning emergency drainage and rescue pump, such as... Figures 1 to 8 As shown, the system includes a rescue pump 1, a water inlet hood 2, a drain pipe 3, an outer baffle cleaning assembly, and an inner baffle protection assembly. The output end of the rescue pump 1 is connected to a hollowed-out frustum-shaped water inlet hood 2. The end of the water inlet hood 2 is connected to the drain pipe 3, the outer end of which is used for external water pipe drainage. The output shaft and impeller of the rescue pump 1 extend into the drain pipe 3. The outer baffle cleaning assembly is rotatably fitted between the housing of the rescue pump 1 and the drain pipe 3, used to actively clean impurities on the outside of the water inlet hood 2. The outer baffle cleaning assembly includes symmetrically arranged detachable baffle covers 4, a limiting ring 45, and a drive mechanism. The baffle covers 4 are fixed to the outer wall of the drain pipe 3 by the limiting ring 45 and are driven to rotate by the drive mechanism. The inner baffle protection assembly includes a positioning ring 6, a protective cover 60, and an elastic element 61 slidably installed inside the drain pipe 3. The protective cover 60 is connected to... The protective cover 60 is attached to the positioning ring 6 and surrounds the output shaft and impeller of the emergency pump 1. The protective cover 60 has a hollow inverted conical structure design, and its surface aperture is smaller than that of the water inlet cover 2. This facilitates secondary filtration of the impact force of hard objects such as stones on the impeller of the emergency pump 1, thus achieving the purpose of protecting the impeller of the emergency pump 1. An elastic element 61 is connected between the side port of the positioning ring 6 and the inner side of the drain pipe 3. The elastic element 61 is a compression spring, which is used to reset the positioning ring 6 and the protective cover 60 connected to it. Through the dual dynamic cooperation of the baffle cover 4, which can rotate circumferentially around the water inlet cover 2, and the protective cover 60, which can reciprocate axially inside the water inlet cover 2, the emergency pump 1 can be effectively self-cleaned, thus making it suitable for use in complex environments.

[0028] Furthermore, such asFigures 3 to 8 As shown in the drawings, the outer baffle cleaning assembly further comprises an arc-shaped guide rail 40, a fixing member 42 and a connecting sleeve 51. The arc-shaped guide rail 40 is symmetrically arranged on the two baffle covers 4, the two baffle covers 4 are clamped by a clamping groove 41 and a limiting ring 45 on the arc-shaped guide rail 40, and are locked by the fixing member 42. The fixing member 42 is a bolt and a nut, and the two baffle covers 4 can be combined and installed on the limiting ring 45 by using the bolt and the nut. The outer wall of the drain pipe 3 is provided with a groove 30, the connecting sleeve 51 is installed in the groove 30 through a bearing, and the limiting ring 45 is fixed on the connecting sleeve 51, so that flexible installation and disassembly can be achieved, and use is convenient.

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

[0030] Further, as shown in Figure 1 , Figure 5 , Figure 6 and Figure 7 , the driving mechanism comprises 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. The output shaft of the driving motor 5 is sleeved with the gear 50. The gear ring 52 is fixedly sleeved on the connecting sleeve 51, and the gear 50 is engaged with the gear ring 52, for driving 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 shown in Figure 4 and Figure 5 , the positioning structure mainly comprises a positioning column 43 and a positioning hole 44 which are inserted and matched with each other. The positioning column 43 is installed on the side edge of one of the two baffle covers 4, and the side edge of the other baffle cover 4 is provided with the positioning hole 44 corresponding to the positioning column 43. The positioning column 43 can be inserted into the positioning hole 44. The two baffle covers 4 can be precisely combined and installed, and the stability of the combined baffle cover 4 structure can be improved.

[0032] In addition, as shown in Figure 1 and Figure 2 , the two baffle covers 4 are combined and installed on the limiting ring 45 through the positioning column 43 and the positioning hole 44.As shown, further comprising support frame 9, rescue pump 1 and the outer wall of the drain pipe 3 are respectively provided with fixed ring 8, the fixed ring 8 is symmetrically provided with support frame 9, and the support frame 9 is located at the periphery of the two blocking covers 4;Through the support and protection of the support frame 9, the water inlet cover 2 can be in a suspended state, facilitating the convenient installation and anti-extrusion of the blocking cover 4;Further comprising a lifting lug 10, the horizontal axis of the rescue pump 1 and the outer wall of the drain pipe 3 is respectively provided with a lifting lug 10;When in use, the rescue pump 1 can be hoisted and moved by tying the lifting lug 10 with a lifting rope, which is convenient to use.

[0033] After connecting the water outlet end of the drain pipe 3 to the water pipe, the rescue pump 1 can be started to work, and the suction force generated by the rotation of the impeller of the rescue pump 1 can suck water from the water inlet cover 2 and discharge it through the drain pipe 3 and the water pipe;When it is necessary to clean the impurities attached to the outside of the water inlet cover 2, it is only necessary to control the operation of the driving motor 5 to drive the connecting sleeve 51 and the limiting ring 45 to rotate synchronously through the transmission of the gear 50 and the gear ring 52;The blocking cover 4 rotates while blocking the impurities located at the periphery of the water inlet cover 2 outside;And through the design of the outward protruding extension of the outside of the blocking cover 4, it can push away the surrounding impurities while rotating, avoiding the direct attachment of impurities to the blocking cover 4 outside to cause blockage;It is beneficial to realize the self-cleaning function, thereby effectively improving the drainage efficiency of the rescue pump 1 and achieving the effect of energy saving to a certain extent;And this design can also significantly improve the efficiency of rescue and disaster relief, avoid the blockage of the blocking cover 4 to reduce the drainage efficiency, and thus increase the energy consumption.

[0034] In addition, the connecting sleeve 51 can also drive the wave ring 7 to rotate synchronously, and 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 vibrate axially along the water inlet cover 2;Through this vibrating filtering method, not only can the impurities be effectively prevented from directly adhering to the protective cover 60, but also the suction of hard objects such as stones into the impeller of the rescue pump 1 can be effectively avoided, which is beneficial to further improve the self-cleaning efficiency of the rescue pump 1, thereby minimizing the drainage time within a certain range, and thus achieving the purpose of saving energy consumption.

[0035] When the rescue pump 1 is used up, the rescue pump 1 and the driving motor 5 are turned off, and the blocking cover 4 can be disassembled for convenient maintenance of the interior of the rescue pump 1.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
