Description

Technical Field

[0001] The utility model relates to the technical field of water pump protection, in particular to a high-pressure resistant explosion-proof water pump. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. When using a water pump underwater, the water pressure will cause the water pump to be under pressure. At the same time, there are many particles underwater, which will enter the inside of the water pump, thereby greatly reducing the service life of the water pump. At the same time, water will enter the motor inside the water pump, causing the motor to be damaged and explode. Therefore, the water pump needs to be resistant to high pressure and explosion-proof.

[0003] When the existing submersible pump is working, it only sets a filter screen at the water inlet to filter impurities in the water body, which has poor filtering effect, does not protect the shell of the submersible pump, and is inconvenient to disassemble the submersible pump device. The shell is easily washed away by water, causing impurities to enter the submersible pump.

[0004] The existing patent (Announcement No.: CN208734568U) is an explosion-proof submersible pump. By setting a box, a water inlet, a coarse filter, a filter frame and a fine filter, the submersible pump is fixedly installed inside the box to provide external protection for the submersible pump. When the submersible pump is used in a water body, water enters the box through the water inlet on the box. The coarse filter arranged inside the box blocks large particles of impurities in the water outside the box. The water entering the box is filtered through the fine filter on the filter frame. First, large particles of impurities are prevented from entering the box and directly contacting the casing of the submersible pump, thereby avoiding corrosion and wear of the casing of the submersible pump, and also preventing impurities from entering the interior of the submersible pump and causing wear on parts, thereby avoiding serious wear of the seals and causing water to enter the explosion-proof motor.

[0005] In view of the above problems, the existing patent provides a solution, but when in use, it only filters water through the cooperation of the water inlet hole and the coarse filter. When it is underwater, the water pressure will cause water to quickly enter the interior of the protective outer box, which will cause damage to the coarse filter in the long run, so it needs to be improved.

[0006] Therefore, a high-pressure explosion-proof water pump is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a high-pressure explosion-proof water pump, which can solve the problem that the existing high-pressure explosion-proof water pump only filters water by cooperating with a water inlet hole and a coarse filter when in use.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 7 , the utility model provides a technical solution:

[0032] A high-pressure explosion-proof water pump comprises a water pump body 1, a protective component 2 for improving the high-pressure resistance and explosion-proof property of the water pump is arranged outside the water pump body 1, and a disassembly component 3 for performing secondary protection on the water pump body 1 is arranged inside the protective component 2;

[0033] The protective assembly 2 includes a protective shell 201, a flared groove 202, a connecting groove 203, a coarse filter screen 204, a first fine filter screen 205, a triangular cavity 206 and a water inlet groove 207. The protective shell 201 is arranged on the outside of the water pump body 1, the flared groove 202 is opened on the outer wall of the protective shell 201, the connecting groove 203 is opened at one end of the flared groove 202, the coarse filter screen 204 is bolted to the inner wall of the protective shell 201, the first fine filter screen 205 is arranged on one side of the coarse filter screen 204, the triangular cavity 206 is bolted to the outer wall of the protective shell 201, the water inlet grooves 207 are evenly distributed on the outer wall of the triangular cavity 206, and the triangular cavity 206 is connected to the flared groove 202.

[0034] Specifically, Figure 7 As shown, a reinforcing rib 4 is welded on the inner top wall of the triangular cavity 206 , and the bottom end of the reinforcing rib 4 is welded to the inner bottom wall of the triangular cavity 206 .

[0035] Specifically, Figure 6 As shown, four extension rods 7 are evenly distributed at the bottom of the water pump body 1 to reduce the contact area between the protective shell 201 and the bottom of the water, and a rectangular frame 8 is welded at the bottom of the extension rods 7 to improve the stability of the protective shell 201.

[0036] Specifically, Figure 1 As shown, a connecting rod 9 is welded to the top of the protective shell 201 , and a hook ring 10 is welded to the top of the connecting rod 9 .

[0037] Specifically, Figure 1 As shown, a rectangular groove 11 is formed on the outer wall of the protective shell 201 , and a tempered glass 12 is bonded inside the rectangular groove 11 .

[0038] Specifically, Figure 1 As shown, four pointed cones 13 are evenly distributed on the bottom of the rectangular frame 8 to improve the stability of the rectangular frame 8 .

[0039] When the device is operating underwater, the pointed cone 13 will contact the bottom of the water, so that the protective shell 201 is fixed. At this time, the extension rod 7 and the rectangular frame 8 can improve the stability of the protective shell 201. Because of the effect of atmospheric pressure, the external water will enter the interior of the water pump body 1 through the expansion groove 202 and the connecting groove 203. At this time, the coordinated use of the triangular cavity 206 and the water inlet groove 207 can effectively slow down the speed of the water flow and prevent the water pump body 1 from being damaged due to the fast water flow speed. Then the reinforcing rib 4 can increase the strength of the triangular cavity 206 to prevent it from being damaged by water pressure.

[0040] Specifically, Figure 4 and Figure 6 As shown, the disassembly and assembly component 3 includes a first protective shell 301, a second protective shell 302, a first mounting ring 303, a second mounting ring 304 and an anti-rust bolt 305. The first protective shell 301 and the second protective shell 302 are both arranged on the outside of the water pump body 1. The first mounting ring 303 and the second mounting ring 304 are respectively welded to one end of the first protective shell 301 and the second protective shell 302. The anti-rust bolt 305 is threadedly connected to the inside of the first mounting ring 303 and the second mounting ring 304. The first protective shell 301 is bolted to the inner top wall of the protective shell 201.

[0041] Specifically, Figure 6 As shown, a second fine filter screen 5 is provided at the bottom of the second protective shell 302 , and a drain pipe 6 is provided on the outer wall of the second protective shell 302 , one end of the drain pipe 6 extends to the outside of the protective shell 201 and is connected to the protective shell 201 .

[0042] When in use, the water pump is placed inside the first protective shell 301 and the second protective shell 302, and then the first mounting ring 303 and the second mounting ring 304 are installed together through the anti-rust bolts 305 to protect the water pump body 1. Then, when the water pump body 1 is started, the external water will also be filtered by the second fine filter 5, and then transported to the pipeline connected to the outside through the drain pipe 6, thereby protecting the water pump body 1 and preventing the water pump body 1 from being blocked.

[0043] By adopting the above technical solution, the problem that the existing high-pressure explosion-proof water pump only filters water through the cooperation of the water inlet hole and the coarse filter 204 when in use is solved, and when it is located underwater, the water pressure will cause water to quickly enter the interior of the protective outer box, which will cause damage to the coarse filter 204 in the long run.

[0044] Working principle: When the device is operated underwater, the water pump is placed inside the first protective shell 301 and the second protective shell 302, and then the first mounting ring 303 and the second mounting ring 304 are installed together through the anti-rust bolt 305 so that the water pump body 1 is protected. Then when the water pump body 1 is started, the external water will also be filtered by the second fine filter 5, and then transported to the pipeline connected to the outside through the drain pipe 6, which plays a role in protecting the water pump body 1 and preventing the water pump body 1 from being blocked. Then the pointed cone 13 will contact the bottom of the water, so that the protective shell 201 is fixed. At this time, the extension rod 7 and the rectangular frame 8 can improve the stability of the protective shell 201. Due to the effect of atmospheric pressure, the external water will enter the interior of the water pump body 1 through the expansion groove 202 and the connecting groove 203. At this time, the coordinated use of the triangular cavity 206 and the water inlet groove 207 can effectively slow down the speed of the water flow, and prevent the first protective shell 301 and the second protective shell 302 from being hit hard due to the fast water flow speed. Then the reinforcing rib 4 can increase the strength of the triangular cavity 206 to prevent it from being damaged by water pressure.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
