DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] Embodiment 1: In view of the fact that the prior art cannot reduce the internal pressure of the pump body, when the pressure inside the pump body increases, the pressure inside the pump body cannot be reduced, which may easily lead to excessive pressure inside the pump body and affect the normal use of the automobile water pump. To solve this problem, the following technical solution is proposed:
[0028] Refer to the instruction manual Figure 1-Figure 7 , an automobile water pump with a pressure protection mechanism, such as Figure 1 and Figure 2 As shown, it comprises a pump body 1, the top of the pump body 1 is connected with a water inlet pipe 2, the bottom of the pump body 1 is connected with a drain pipe 3, the inner wall of the pump body 1 is provided with a buffer mechanism 4, and both sides of the pump body 1 are provided with a pressure reducing drain mechanism 5;
[0029] like Figure 3 and Figure 4 As shown, the buffer mechanism 4 includes a plurality of buffer grooves 41 opened on the inner wall of the pump body 1, the plurality of buffer grooves 41 are interconnected with the interior of the pump body 1, the plurality of buffer grooves 41 are arranged in a ring-shaped and equidistant manner on the inner circumferential surface of the pump body 1, baffles 42 are slidably installed on the inner walls of the plurality of buffer grooves 41, the plurality of baffles 42 are arranged in an arc shape, the outer walls of the plurality of baffles 42 are in contact with the inner walls of the buffer grooves 41, and the outer walls of the plurality of baffles 42 are arranged corresponding to the inner wall of the pump body 1. When the water pressure in the pump body 1 increases, the water in the pump body 1 squeezes the outer walls of the baffles 42, and then the plurality of baffles 42 slide toward the inside of the buffer grooves 41, that is, the water in the pump body 1 is dispersed in the buffer grooves 41 to reduce the water pressure.
[0030] like Figure 3 and Figure 4 As shown, the outer walls of the plurality of baffles 42 are provided with a limiting frame 43, and the limiting frame 43 is fixedly mounted on the inner wall of the pump body 1, and the limiting frame 43 and the buffer groove 41 are arranged corresponding to each other, and the limiting frame 43 is arranged with a central opening, and the area of the limiting frame 43 is larger than the area of the baffle 42, and one side of the limiting frame 43 is in contact with the outer wall of the baffle 42, and the baffle 42 is restricted by the limiting frame 43, thereby preventing the baffle 42 from detaching from the buffer groove 41.
[0031] like Figure 3 and Figure 4As shown, a push rod 44 is fixedly installed on one side of the baffle 42, and the push rod 44 is arranged in a horizontal state. A sleeve 45 is slidably installed on one side of the push rod 44, and the sleeve 45 is fixedly installed on the inner wall of the buffer groove 41. The sleeve 45 and the push rod 44 are arranged in parallel with each other. The push rod 44 is driven by one side of the baffle 42 to slide into the sleeve 45, so that the baffle 42 can move backward horizontally and stably.
[0032] like Figure 3 and Figure 4 As shown, a buffer spring 46 is fixedly installed on one side of the baffle 42, and the buffer spring 46 is fixedly installed on the inner wall of the buffer groove 41. The buffer spring 46 is arranged in a horizontal state, and the buffer spring 46 and the baffle 42 are arranged perpendicular to each other. Then, the baffle 42 moves backward to compress the buffer spring 46 to shrink.
[0033] like Figure 3 and Figure 4 As shown, a scale plate 47 is fixedly installed on one side of the baffle 42, and the scale plate 47 passes through the outer wall of the pump body 1. The scale plate 47 is arranged in a horizontal state, and the scale plate 47 and the baffle 42 are arranged perpendicular to each other. The scale plate 47 is synchronously moved backward by the backward movement of the baffle 42 and extends out from the outer wall of the pump body 1. That is, the moving distance of the baffle 42 can be intuitively understood through the scale plate 47, that is, the water pressure in the pump body 1 can be understood.
[0034] like Figure 5 and Figure 6 As shown, the pressure reducing drainage mechanism 5 includes lead-out grooves 51 provided on both sides of the bottom of the buffer groove 41, the lead-out grooves 51 penetrate the outer wall of the pump body 1, and the inner walls of the two lead-out grooves 51 are fixedly installed with water pipes 52, so that the water pushed by the water pressure in the pump body 1 enters the buffer groove 41, and then the water pushes the baffle 42 to continue to move backward and pass over the water pipes 52 on the lead-out groove 51, that is, the water can directly enter the water pipes 52, one side of the two water pipes 52 is respectively connected to the inner walls on both sides of the drain pipe 3, and the other side of the water pipes 52 is located at the bottom of the buffer groove 41, and a groove is provided on the top of the water pipe 52, and the groove is connected to the inside of the buffer groove 41. The water pipe 52 discharges the water passing through into the drain pipe 3 for discharge, and the water pressure in the pump body 1 is reduced by dispersing the water in the pump body 1 into the drain pipe 3.
[0035] like Figure 5 and Figure 6As shown, a cover plate 53 is provided on the top of the water pipe 52, and the cover plate 53 is slidably installed on the inner wall of the buffer groove 41. The area of the cover plate 53 is larger than the area of the groove opened on the top of the water pipe 52. A support spring 54 is fixedly installed on one side of the cover plate 53, and the support spring 54 is fixedly installed on the inner wall of the buffer groove 41. The cover plate 53 temporarily covers the top of the water pipe 52 under the support of the support spring 54, and then the baffle 42 moves backward to push the cover plate 53 to move backward synchronously and compress the support spring 54 to open the water pipe 52.
[0036] like Figure 6 and Figure 7 As shown, a sealing plate 55 is provided on one side of the water pipe 52, and the sealing plate 55 is arranged in a vertical state. The outer wall of the sealing plate 55 fits with the inner wall of the water pipe 52, and a plurality of sliding rods 56 are fixedly installed on one side of the sealing plate 55. The plurality of sliding rods 56 are slidably installed on the inner wall of the water pipe 52. The sealing plate 55 is used to seal one side of the water pipe 52 to prevent the water in the drainage pipe 3 from reversely entering the sealing plate 55. When the water in the pump body 1 is discharged from the water pipe 52, the sealing plate 55 is opened by pressure, driving the plurality of sliding rods 56 to slide out, so that the water pipe 52 can be connected with the drainage pipe 3 for drainage.
[0037] In a specific implementation, when the water pressure in the pump body 1 increases, the water in the pump body 1 squeezes the outer wall of the baffle 42, and then the multiple baffles 42 slide into the inside of the buffer groove 41, and the push rod 44 is driven to slide into the sleeve 45 through one side of the baffle 42, so that the baffle 42 can move backward horizontally and stably, and the baffle 42 moves backward to compress the buffer spring 46 to shrink, that is, the water in the pump body 1 is dispersed in the buffer groove 41 to reduce the water pressure, and the baffle 42 moves backward to drive the scale plate 47 to move backward synchronously and extend from the outer wall of the pump body 1, that is, the moving distance of the baffle 42 can be intuitively understood through the scale plate 47, that is, the water pressure in the pump body 1 can be understood;
[0038] At the same time, the water pushed by the water pressure in the pump body 1 enters the buffer groove 41, and the baffle plate 42 moves backward to push the cover plate 53 to move backward synchronously and compress the support spring 54 and cross the water pipe 52 on the outlet groove 51, that is, the water can directly enter the water pipe 52, and the water in the water pipe 52 drives the multiple sliding rods 56 to slide out through the pressure-pushing sealing plate 55, so that the water pipe 52 can be connected to the drain pipe 3 for drainage, and the water in the pump body 1 is dispersed and discharged into the drain pipe 3, thereby reducing the water pressure in the pump body 1.
