Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment and toys, in particular to a long-distance remote-controlled water rocket. Background Art

[0002] Water rockets, also known as pneumatic water jet rockets or water-propelled rockets, utilize discarded beverage bottles as their power chambers. They are a well-known example in physics teaching and can foster students' interest in physics. Water rockets are model rockets that launch using the pneumatic water jet principle. Launching a water rocket provides a simple, intuitive, and comprehensive demonstration of the principles of rocket testing and flight. This method enhances students' understanding of the rocket testing and flight process, improving teaching effectiveness through engaging learning.

[0003] A common water rocket includes a round water storage bottle body and a round bottle mouth, and the middle section of the bottle mouth is provided with an annular clamping groove. The launching device includes an outer sleeve and an inner sleeve. When the water rocket is assembled and pressurized, the outer sleeve and the inner sleeve are socketed and locked together, and the open round bottle mouth filled with water is manually clamped on the inner sleeve, and then manually inflated and pressurized. When the air pressure is pressurized to a predetermined level, the operator turns on the launching switch by hand, and the socket locking relationship between the outer sleeve and the inner sleeve is released. The water rocket is separated from the inner sleeve under the action of the air pressure and launched. Since the launcher has to operate the launching switch at close range during the launching process, it is easy to cause injury to the launcher when the launching air pressure is released outward. Utility Model Content

[0004] The purpose of the utility model is to provide a long-distance remote-controlled water rocket, which solves the problem that the existing water rockets are likely to cause harm to the launcher during launch.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A remote-controlled water rocket comprises a water rocket body and a launching device, wherein the water rocket body comprises a circular water storage bottle body and a circular bottle mouth, wherein the middle section of the bottle mouth is provided with an annular clamping groove; the launching device comprises an outer sleeve and an inner sleeve, wherein the inner sleeve comprises an upper mounting portion and a lower sealed one-way inflation valve, wherein a positioning through hole is provided on the inner side wall of the upper mounting portion;

[0007] The outer sleeve is fixed in position, and the upper mounting portion of the inner sleeve is movably sleeved within the outer sleeve. A transverse semi-counterfeit hole is provided on the inner wall of the outer sleeve, and a steel ball pre-tightening spring is provided in the semi-counterfeit hole. The inner side of the sliding steel ball is pre-tightened against the outer end of the steel ball pre-tightening spring, and the inner end of the steel ball pre-tightening spring is pressed against the bottom of the transverse semi-counterfeit hole. The outer side of the sliding steel ball is reserved on the outer side of the transverse semi-counterfeit hole under the action of the steel ball pre-tightening spring, and the positioning through hole matches the outer side of the sliding steel ball. When the water rocket is assembled in a pressurized state, the upper end of the sealed one-way inflation valve is sealed with the lower end of the bottle mouth, and the annular clamping groove in the middle section of the bottle mouth is matched and clamped and fixed with the outer side of the sliding steel ball. A remote controller is also included. When the water rocket is in a launching state, the remote controller controls the inner sleeve to move upward relative to the outer sleeve, and the annular clamping groove in the middle section of the bottle mouth is disengaged from the steel ball.

[0008] Adopting the automatic quick locking structure of the above-mentioned outer sleeve and inner sleeve, when the water rocket needs to be assembled into a pressurized state, it is only necessary to press the circular bottle mouth of the water rocket body downward into the inner sleeve. During the pressing process, the bottle mouth overcomes the elastic force of the steel ball pre-tightening spring, so that the annular clamping groove in the middle section of the bottle mouth matches and is clamped and fixed with the outer side of the sliding steel ball. At this time, the upper end of the sealed one-way inflation valve is sealed with the lower end of the bottle mouth, which is convenient for directly using a pressure pump (air cylinder) to pressurize the water storage bottle body through the sealed one-way inflation valve. When the air pressure is pressurized to a predetermined level and ready to be launched, the operator stays away from the water rocket and uses a remote controller to move the inner sleeve upward relative to the outer sleeve to overcome the elastic force of the steel ball pre-tightening spring. The annular clamping groove in the middle section of the bottle mouth is disengaged from the steel ball, and the water rocket is launched under the action of air pressure. Since the automatic quick locking structure is convenient for rapid installation, locking and disengagement under the action of external force, and at the same time, the inner sleeve can be controlled to move upward relative to the outer sleeve through a remote controller, thereby quickly releasing the lock, the launcher can operate away from the dangerous area, and the air pressure released outward during the water rocket launch can be avoided to cause harm to the launcher.

[0009] Furthermore, a launching platform is also defined, that is, the water rocket also includes a base, left and right vertical support plates, a first mounting seat and a second mounting seat, the lower ends of the left and right vertical support plates are fixedly connected to the upper surface of the base, the first mounting seat and the second mounting seat are hinged in parallel to the left and right vertical support plates, wherein the first mounting seat is installed on the upper sections of the left and right vertical support plates, and the second mounting seat is installed on the middle sections of the left and right vertical support plates; the longitudinal cross-sections of the first mounting seat and the second mounting seat are both door-shaped, the first mounting seat includes a first upper panel and first side panels on both sides, the second mounting seat includes a second upper panel and second side panels on both sides, a first mounting hole is provided on the first upper panel, the outer sleeve is fixed in the first mounting hole, the second upper panel is provided with a second mounting hole, and the lower section of the inner sleeve is movably fixed in the second mounting hole.

[0010] The use of the above-mentioned launching platform can further optimize the structure of the launching device, and the first mounting seat and the second mounting seat on the platform are used to fix the outer sleeve and install the inner sleeve.

[0011] Furthermore, the remote controller is defined as a hydraulic device, which includes a hydraulic auxiliary pump, a push rod and a hydraulically operated main pump, wherein the hydraulic auxiliary pump is fixed on the upper surface of the second upper panel, the push rod is arranged at the upper end of the hydraulic auxiliary pump, the upper end of the push rod is supported at the bottom of the inner sleeve upper section mounting portion, and the push rod moves upward and extends under the control of the hydraulically operated main pump. In this hydraulic control method, the hydraulically operated main pump connects the oil pressure to the hydraulic auxiliary pump through the hydraulic oil pipe, and the hydraulic auxiliary pump drives the push rod to move, thereby pushing the inner sleeve to move upward relative to the outer sleeve. The hydraulic mechanism is simple and stable, with a strong driving force, which can better ensure the stability of the launch.

[0012] In addition, considering the problem of returning the inner sleeve to its original position relative to the outer sleeve, the limiting launch device also includes an annular return spring, the lower end of which is fixedly supported on the lower section of the inner sleeve, and the upper end of which is limited to the lower end of the outer sleeve. When the hydraulic external force is removed, under the action of the annular return spring, the inner sleeve moves downward relative to the outer sleeve to a quick-locking state, that is, the outer side of the sliding steel ball is locked when it is retained inside the inner sleeve under the action of the steel ball preload spring, making it convenient to directly lock the annular engaging groove provided in the middle section of the bottle mouth with the outer side of the sliding steel ball next time.

[0013] In addition, water rockets are usually launched vertically at 90 degrees, and it is only necessary to place the base on a flat surface. However, sometimes a certain tilt angle is considered for launch. In order to better ensure the tilt angle, a rotation space is reserved between the second mounting base and the base, and a rotation space is reserved between the first mounting base and the second mounting base. Since the first mounting base and the second mounting base are hinged in parallel to the left and right vertical support plates, there is rotation space between the first mounting base, the second mounting base and the base, so the first mounting base and the second mounting base can be rotated to a suitable angle, for example, to 75 degrees for launch, as long as the first mounting base and the second mounting base are kept parallel.

[0014] Furthermore, in order to better determine the launch angle, an angle measuring scale is provided on the outer side of the first side panel and the second side panel, and an angle pointer is provided at a position corresponding to the angle measuring scale on the vertical support plate, and the angle measuring scale and the angle pointer match.

[0015] By adopting the above technical solution, the water rocket can fly to a specific target more accurately or achieve the optimal launch distance. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a long-distance remote-controlled water rocket includes a water rocket body and a launching device. The water rocket body includes a circular water storage bottle body 1 and a circular bottle mouth 2. The middle section of the bottle mouth 2 is provided with an annular clamping groove 21; the launching device includes an outer sleeve 3 and an inner sleeve 4. The inner sleeve 4 includes an upper mounting portion 41 and a lower sealed one-way inflation valve 42. The inner side wall of the upper mounting portion 41 is provided with a positioning through hole 43.

[0023] The outer sleeve 3 is fixed in position, and the upper mounting portion 41 of the inner sleeve 4 is movably sleeved inside the outer sleeve 3. A transverse semi-sunk hole 31 is provided on the inner wall of the outer sleeve 3, and a steel ball preload spring 32 and a sliding steel ball 33 are provided in the semi-sunk hole 31. The inner side of the sliding steel ball 33 is preloaded against the outer end of the steel ball preload spring 32, and the inner end of the steel ball preload spring 32 is pressed against the bottom of the transverse semi-sunk hole 31. The outer side of the sliding steel ball 33 is reserved outside the transverse semi-sunk hole under the action of the steel ball preload spring 32, and the positioning through hole 43 matches the outer side of the sliding steel ball 33; in the water rocket assembly When pressurized, the upper end of the sealed one-way inflation valve 42 seals against the lower end of the bottle mouth 2, and the annular engaging groove 21 in the middle section of the bottle mouth 2 engages and secures with the outer side of the sliding steel ball 33. A hydraulic actuator is also included, comprising a hydraulic auxiliary pump 51, a push rod 52, and a hydraulically operated main pump 53. The hydraulic auxiliary pump 51 is fixed to the upper surface of the second upper panel, and the push rod 52 is disposed at the upper end of the hydraulic auxiliary pump 51. The push rod's upper end is supported by the bottom of the inner sleeve upper mounting portion 41. During the water rocket launch, the push rod 52 moves upward under the control of the hydraulically operated main pump 53. This hydraulic control method transmits oil pressure from the hydraulically operated main pump 51 to the hydraulic auxiliary pump 51 via a hydraulic oil pipe 54. The hydraulic auxiliary pump 51 drives the push rod 52, thereby pushing the inner sleeve 4 upward relative to the outer sleeve 3. The hydraulic mechanism is simple and stable, with strong driving force, which can better ensure launch stability.

[0024] Adopting the automatic quick locking structure of the above-mentioned outer sleeve 3 and inner sleeve 4, when the water rocket needs to be assembled into a pressurized state, it is only necessary to press the circular bottle mouth 2 of the water rocket body downward into the inner sleeve 4. During the pressing process, the bottle mouth 2 overcomes the elastic force of the steel ball preload spring 32, so that the annular clamping groove 21 in the middle section of the bottle mouth is matched with the outer side of the sliding steel ball 33 and fixed. At this time, the upper end of the sealed one-way inflation valve 42 is sealed with the lower end of the bottle mouth 2, which is convenient for directly using a pressure pump (air cylinder) to pressurize the water storage bottle body through the sealed one-way inflation valve. When the air pressure is pressurized to a predetermined level and ready to be launched, the operator stays away from the water rocket and uses the remote controller to move the inner sleeve 3 upward to overcome the elastic force of the steel ball preload spring 32. The annular clamping groove 21 in the middle section of the bottle mouth 2 is disengaged from the steel ball 33, and the water rocket is launched under the action of air pressure. Since the automatic quick locking structure is convenient for rapid installation, locking and disengagement under the action of external force, and at the same time, the inner sleeve 3 can be controlled to move upward relative to the outer sleeve 3 by a remote controller, thereby quickly releasing the lock, the launcher can operate away from the dangerous area, and the air pressure released outward during the water rocket launch can be avoided to cause harm to the launcher.

[0025] Furthermore, a launching platform is also defined, that is, the water rocket also includes a base 6, left and right vertical support plates 7, a first mounting seat 8 and a second mounting seat 9, the lower ends of the left and right vertical support plates 7 are fixedly connected to the upper surface of the base 6, and the first mounting seat 8 and the second mounting seat 9 are hinged in parallel to the left and right vertical support plates 7, wherein the first mounting seat 8 is installed on the upper section of the left and right vertical support plates 7, and the second mounting seat 9 is installed on the middle section of the left and right vertical support plates 7; the longitudinal cross-sections of the first mounting seat 8 and the second mounting seat 9 are both door-shaped, the first mounting seat 8 includes a first upper panel and first side panels on both sides, the second mounting seat 9 includes a second upper panel and second side panels on both sides, a first mounting hole is provided on the first upper panel, the outer sleeve is fixed in the first mounting hole, and a second mounting hole is provided on the second upper panel, and the lower section of the inner sleeve is movably fixed in the second mounting hole.

[0026] The use of the above-mentioned launching platform can further optimize the structure of the launching device, and the first mounting seat and the second mounting seat on the platform are used to fix the outer sleeve 3 and install the lower section of the inner sleeve 4.

[0027] In addition, considering the problem of returning the inner sleeve 4 to its original position relative to the outer sleeve 3, the limited launch device further includes an annular return spring 10, the lower end of which is fixedly supported on the lower section of the inner sleeve 4, and the upper end of which is limited to the lower end of the outer sleeve 3. When the hydraulic external force is removed, under the action of the annular return spring 10, the inner sleeve 4 moves downward relative to the outer sleeve 3 to a quick-locking state, that is, the outer side of the sliding steel ball 33 is locked in the state retained within the inner sleeve 3 under the action of the steel ball preload spring 32, facilitating the next direct locking of the annular engaging groove 21 provided in the middle section of the bottle mouth with the outer side of the sliding steel ball.

[0028] In addition, water rockets are usually launched vertically at 90 degrees, and it is only necessary to place the base 6 on a flat surface. However, sometimes a certain tilt angle is considered for launch. In order to better ensure the tilt angle, it is limited that there is a rotation space between the second mounting seat 9 and the base 6, and there is a rotation space between the first mounting seat 8 and the second mounting seat 9. Since the first mounting seat 8 and the second mounting seat 9 are hinged in parallel on the left and right vertical support plates 7, there is a rotation space between the first mounting seat 8, the second mounting seat 9 and the base 6, so the first mounting seat 8 and the second mounting seat 9 can be rotated to a suitable angle, for example, to 75 degrees for launch, as long as the first mounting seat 8 and the second mounting seat 9 are parallel.

[0029] Furthermore, in order to better determine the launch angle, an angle measuring scale 18 is provided on the outer side of the first side panel and the second side panel, and an angle pointer 19 is provided at a position corresponding to the angle measuring scale on the vertical support plate, and the angle measuring scale 18 and the angle pointer 19 match.

[0030] By adopting the above technical solution, the launching angle of the water rocket can be adjusted so that the water rocket can fly to a specific target more accurately or achieve the optimal launching distance.

[0031] When using the present technical solution, when the water rocket needs to be assembled into a pressurized state, it is only necessary to press the circular bottle mouth 2 of the water rocket body downward into the inner sleeve 4. During the downward pressing process, the bottle mouth 2 overcomes the elastic force of the steel ball preload spring 32, so that the annular clamping groove 21 in the middle section of the bottle mouth is matched with the outer side of the sliding steel ball 33 and fixed. At this time, the upper end of the sealed one-way inflation valve 42 is sealed with the lower end of the bottle mouth 2, which is convenient for directly using a pressure pump (air cylinder) to pressurize the water storage bottle body through the sealed one-way inflation valve. When the air pressure is pressurized to a predetermined level and ready to be launched, the operator stays away from the water rocket and uses the remote controller to move the inner sleeve 3 upward to overcome the elastic force of the steel ball preload spring 32. The annular clamping groove 21 in the middle section of the bottle mouth 2 is disengaged from the steel ball 33, and the water rocket is launched under the action of air pressure. Since the automatic quick locking structure is convenient for rapid installation, locking and disengagement under the action of external force, and at the same time, the inner sleeve 3 can be controlled to move upward relative to the outer sleeve 3 by a remote controller, thereby quickly releasing the lock, the launcher can operate away from the dangerous area, and the air pressure released outward during the water rocket launch can be avoided to cause harm to the launcher.

The above examples are only intended to help you understand the core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
