Description

Technical Field

[0001] The utility model belongs to the technical field of police equipment, and particularly relates to a water tank bullet catching device. Background Art

[0002] As one of the police equipment, guns need to be strictly managed. Before the existing guns are used, files need to be established for them. Currently, the method of gun filing is to judge from which gun a bullet is fired by the unique trace characteristics left when the bullet is fired through the barrel.

[0041] The following describes the preferred embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0042] The present utility model provides a water tank bullet grabbing device, as Figures 1 to 3 shown, including: box body 1, shooting entrance 2, vacuum water pump 3, water filter 6, air filtration component 5 and control circuit 7; the shooting entrance 2 is inclinedly arranged at one end of the box body 1; the vacuum water pump 3 is arranged at the other end or the side wall of the box body 1 and is communicated with the box body 1; the water filter 6 is arranged beside the box body 1; the air filtration component 5 is arranged at the other end or the side wall of the box body 1 and is located at the same end as the vacuum water pump 3; the control circuit 7 is arranged on the box body 1 and is connected to the vacuum water pump 3 and the air filtration component 5 to drive the vacuum water pump 3 and the air filtration component 5.

[0043] When the water tank bullet grabbing device is in use, the vacuum water pump 3 is turned on to drive the water in the water tank 1 to flow to generate a vortex, increasing the resistance of the bullet in the water, so that the speed of the bullet can be quickly reduced, which is more beneficial to protecting the bullet marks. And since the resistance of the water in the water tank can be adjusted by the vacuum water pump 3 with different gears, there is no need to use a large-volume water tank, and it can be applicable to guns with different powers. At the same time, a water filter 6 and a filtration device are also provided. When the bullet shoots into the water tank, harmful substances will be generated. At this time, the harmful substances can be adsorbed by the water filter 6, thereby reducing the frequency of changing water; the harmful gases generated during the filing process are filtered by the air filtration component 5.

[0044] Specifically, the box body 1 is provided with a drainage port 102. The box body 1 is made of 1 / 4“ (0.63 cm) stainless steel plate, and the overall steel consumption is reduced by 25%. It has the advantages of greater strength, stronger anti-impact and bending ability, and greater penetration resistance. And for each welding joint on the box body 1, MIG (Metal Inert Gas Welding) welding is performed four times inside and outside, and then TIG (Tungsten Inert Gas Welding) welding is performed inside and outside. Significantly enhances the strength of the tank body and improves the long-term leak-proof performance. The multiple welding technology ensures the stability of the box body, enabling the box body to withstand greater impact force.

[0045] The shooting entrance 2 is made of 0.63 cm thick stainless steel to ensure maximum safety. The shooting entrance 2 and the box 1 are not designed to be vertical, so that the shooting is directed to be fired along the diagonal line of the ship so that the bullet travels the longest path through the water.

[0046] The flow rate of the vacuum water pump 3 is not less than 10gpm (about 2.27m 3 / h) to obtain sufficient pressure to maintain the water flow from the front end to the rear end of the box 1, thereby generating vortices and increasing the resistance of the bullet in the water.

[0047] Furthermore, the box body 1 can be hingedly connected with a box body protection cover 101. The box body protection cover 101 is provided with 167 pounds (75kg), 11 gallons (0.05m 3 ) stainless steel material, will generate 700 pounds (317.5kg) of downward pressure. This force can ensure that the lid remains closed during operation. The reasonable structure of the lid ensures that water or condensate will not be discharged from the box body 1 during shooting, and it can repeatedly absorb the high energy generated by each shooting without damaging the closing mechanism of the cover. The box protection cover 101 is connected to the box body 1 through a pneumatic lifting rod 14, which is controlled by the control circuit to open or close the box protection cover 101.

[0048] The control circuit 7 is connected to a solenoid valve (used to control the flow direction of the gas). When the solenoid valve is opened, the air pump in the pneumatic lifting rod 14 starts working at the same time, and the gas generated by the air pump is transported to the pneumatic lifting rod 14 to open the cover. When the cover is closed, the gas flows to the exhaust port of the air pump through the solenoid valve (used to control the flow direction of the gas), and the pneumatic lifting rod 14 is exhausted and lowered.

[0049] Specifically, the air filter assembly 5 includes: a high-pressure blower 51 and a filter 52; the high-pressure blower 51 and the filter 52 are started or shut down under the control of the control circuit. The high-pressure blower can evacuate the air in the entire water tank within 10 seconds. The blower can absorb lead and particulate matter exposed to the surrounding air when the shooter shoots. The shell of the filter 52 is stainless steel, and the special construction method prevents indoor air particles from entering the atmosphere. The filter 52 includes a 30% pre-filter and a laboratory-certified 99.97% HEPA filter. The working process of the air filter assembly 5 is as follows: through the shooting inlet 2 port, the indoor air is sucked into the box 1, enters the suction side of the high-pressure blower 51 through the pipe, and is then discharged to the filter 52 to achieve air filtration.

[0050] Four shock isolation feet pads 8 are provided at the bottom of the box body 1, and each can bear 2,400 pounds. The box body 1 can be set in a "free floating" state, isolating the box body 1 from the ground and reducing the impact during firing. The shock isolation feet pads 8 are connected to an air compressor. 12 During use, the air hose connected to the air compressor can cause the pneumatic springs in the shock isolation feet pads 8 to expand, thereby achieving the purpose of leveling the entire water tank ammunition catching device.

[0051] As Figure 4 shown, the control circuit 7 includes: a main circuit breaker CB, a high-voltage control unit, a transformer trans, and a low-voltage control unit; the power supply is connected to the high-voltage control unit through the main circuit breaker CB, and the high-voltage control unit is connected to the low-voltage control unit through the transformer trans. The conversion between high voltage and low voltage is achieved through the transformer trans, enabling the same power supply to supply power to the high-voltage control unit and the low-voltage control unit simultaneously. The control circuit 7 is placed in the control electrical box and fixed to the outside of the box body 1.

[0052] Further, the high-voltage control unit includes: a first contactor K1, a second contactor K2, a third contactor K3, a first fuse F1, a second fuse F2, and a third fuse F3; the main circuit breaker CB is sequentially connected to the vacuum water pump 3 through the first fuse F1 and the normally open contact of the first contactor K1; the main circuit breaker CB is sequentially connected to the high-voltage blower 51 through the second fuse F2 and the normally open contact of the second contactor K2; the main circuit breaker CB is sequentially connected to the air compressor through the third fuse F3 and the normally open contact of the third contactor K3; the main circuit breaker CB is connected to one coil of the transformer trans. When it is necessary to start the vacuum water pump 3, the high-voltage blower 51, and the air compressor, just turn on the corresponding switches.

[0053] The low-voltage control unit includes: a fourth fuse F4, a fifth fuse F5, a first switch Q1, a second switch Q2, a white / green indicator light LED1, an LED light group LED2, a two-phase circuit breaker Q, a power switch U1, and an LED illuminance regulator U2; the other coil of the transformer trans is sequentially connected to the fifth fuse F5 and the first switch Q1, and the first switch Q1 is respectively connected to the white / green indicator light LED1 and the coil of the third contactor K3; the first switch Q1 is respectively connected to the coil of the first contactor K1 and the coil of the second contactor K2 through the two-phase circuit breaker Q; the first switch Q1 is connected to the power switch U1 through the second switch Q2; the power switch is connected to the LED illuminance regulator U2, and the LED illuminance regulator U2 is connected to the LED light group LED2 through the fifth fuse F5. By means of the second switch Q2, the opening or closing of the LED light group LED2 can be realized. At the same time, through the LED illuminance regulator U2, the adjustment of the LED illuminance can be realized.

[0054] A lamp slot 9 for placing the LED light group is provided inside the box body 1.

[0055] Inside the box body 1, there is an HDPE (High-Density Polyethylene) pad, which is the bright white HDPE pad 10 and has characteristics such as durability and semi-rigidity. Fixing the HDPE pad 10 in the detachable stainless-steel fitting ensures that the HDPE pad 10 will not move. At the same time, there is no need to use adhesives or sealants, and the HDPE pad 10 can be easily replaced or removed.

[0056] As Figure 5 shown, inside the box body 1, there is a vacuum bullet extractor 4, and multiple bullets can be quickly recovered through the vacuum bullet extractor 4. The integrated vacuum rod can collect at least 180 bullets of different specifications from 12 - 44 Magnum (Magnum) at one time.

[0057] The vacuum bullet extractor 4 is connected to the air path of the vacuum water pump 3. The water path of the vacuum water pump 3 is used to generate a vortex in the water tank 1. The vacuum bullet extractor 4 can be realized by a sealed plastic pipe (which includes a section of hard pipe and a section of flexible pipe). When the pressure lower than the surrounding environment is created in a vacuum tube inside the box body 1 by the vacuum water pump 3, a pressure difference higher than this pressure will be generated in the surrounding environment. Through the pressure difference, when the front part of the plastic pipe sucks in the bullet, the water near the bullet is also sucked in. However, the rear part of the pipe is bent and there is air pressure to hold it. So, only the front part of the whole plastic pipe sucks in water and bullets. Then, pick up the whole pipe and place it on the bullet extractor, and then straighten the pipe. At this time, the sucked bullets and water are discharged into the bullet extractor together, and the water will seep out from the bullet extractor and flow into the water bullet catcher, leaving only the bullets.

[0058] To cooperate with the function of the vacuum bullet extractor 4, a three-way valve can also be set between the control circuit 7 and the vacuum water pump 3 to wrap the plastic pipe around the area to be evacuated, and then open the three-way valve to start. This three-way valve will control the suction direction of the pump. To prevent air from entering the pump and causing failure, the valve should only be turned when the tip of the vacuum bullet extractor 4 is immersed. The bullet extractor can be used to fish out multiple bullets.

[0059] The shooting entrance is connected to a wire-controlled shooting bracket. When conducting firearm archiving, usually each firearm needs to complete six or seven rounds of shooting. For a large number of firearm archivings, it will consume a huge amount of physical strength for police officers. Conducting firearm archiving in a fatigued state is extremely dangerous. By setting up the shooting bracket, when archiving, place the firearm on the shooting bracket to reduce the burden on police officers. The structure of the wire-controlled shooting bracket can refer to the existing technology and will not be elaborated here one by one.

[0060] In summary, the water tank bullet-catching device of the present utility model controls the flow rate of the vacuum water pump to drive the water in the water tank to flow, generating frictional resistance and eddy current resistance, increasing the resistance of the bullet in the water, enabling the speed of the bullet in the box to drop rapidly, effectively avoiding the collision of the bullet with the side wall of the box, and the water flow can protect the fine traces on the surface of the bullet; due to the increased water resistance, it is not necessary to use a larger-volume box to decelerate the bullets fired by sniper rifles (bullets with a flight speed of up to 1000 m / s or other guns with greater power), and it can be applicable to guns with different powers. At the same time, a water filter and an air filtration component are also provided. The water filter adsorbs harmful substances, removes the suspended solids and particulate matter of harmful substances in the water body, reduces turbidity, purifies the water quality, reduces the generation of dirt, algae, rust, etc., so as to purify the water quality and then reduce the frequency of water change; the air filtration component absorbs the white smoke generated in the gun barrel after firing the bullet (when a large number of bullets are fired, a lot of white smoke will block the line of sight, resulting in the interruption of shooting) and filters harmful gases (after the gunpowder is ignited, white smoke and metal particles are generated, and the composition of the white smoke is relatively complex, containing hydrogen, carbon monoxide, oxidizing agent potassium chlorate, smoke agent red phosphorus, etc. that are harmful to the human body) and other air impurities. By absorbing the white smoke, it ensures that the operator can fire a large number of bullets safely without affecting the line of sight, and by filtering, it avoids the situation that the operator absorbs harmful gases for a long time and causes chronic physical damage.

[0061] The above is only a preferred utility model of this application, and it is not intended to limit this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
