Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a protector for a water conservancy hoist. Background Art

[0002] A hydraulic gate hoist is a special device used to control the opening and closing of gates in hydraulic projects. It plays an important role in ensuring the normal operation of hydraulic projects, improving project efficiency and ensuring safety. Therefore, it is an indispensable equipment in hydraulic projects. However, since hydraulic gate hoists are usually installed outdoors, corresponding protectors are required to reduce damage to the equipment caused by external wind, sun or rain, thereby extending the service life of the equipment.

[0003] After searching, an existing patent (Announcement No.: CN221029998U) discloses a safety protection device for a gate hoist of a water conservancy project, comprising a shell enclosed around the gate hoist, a rectangular hole for the threaded rod of the gate hoist to extend out of the top of the shell, and a telescopic structure for protecting the threaded rod and cooperating with the lifting and lowering of the threaded rod; the outer wall of the shell is connected to the lifting structure; the telescopic structure is fixedly connected to a magnetic component, and when the threaded rod rises or falls, its top end is attracted to the magnetic component, driving the telescopic structure to rise or fall. The rise of the threaded rod can drive the second and third containers to rise vertically upward. Regardless of whether the threaded rod rises or falls, it can be effectively protected in the telescopic structure. The top end of the threaded rod generates an adsorption force with the magnetic component, and when the threaded rod falls, it can drive the second and third containers to slide and fall, making it convenient and quick to use.

[0004] However, in the above scheme, there are no baffles on the front and back of the protective device, which results in some rain being blown from the front and back of the protective device to the hydraulic gate hoist due to factors such as strong winds when it rains, and strong sunlight will also shine on the hydraulic gate hoist, resulting in poor protection effect on it, and unable to achieve more comprehensive shielding protection, which affects the service life of the hydraulic gate hoist.

[0005] In view of this, the utility model proposes a protector for a hydraulic hoist. Utility Model Content

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0027] The preferred embodiment of the protector for the hydraulic hoist provided by the utility model is as follows Figures 1 to 5 As shown: A protector for a water conservancy opening and closing machine, comprising a protective box 3; a door body 5 fixedly connected to the front of the protective box 3 by a hinge; a telescopic protective tube 2 fixedly connected to the top of the protective box 3, and a top cover 1 fixedly connected to the top of the telescopic protective tube 2; ventilation holes 10 symmetrically opened on both sides of the protective box 3; rain shield components 4 symmetrically assembled on both sides of the protective box 3, the rain shield components 4 are used to shield the ventilation holes 10 when it rains heavily, thereby reducing the possibility of rainwater splashing from the ventilation holes 10 into the interior of the protective box 3.

[0028] The rain shield assembly 4 includes: a slide groove 407 symmetrically opened at the lower end of both sides of the protective box 3; a slide rod 404 fixedly connected to the inner wall of the slide groove 407; a slider 405 slidably connected to the surface of the slider 404; a return spring 406 wrapped around the surface of the slider 404, and the two ends of the return spring 406 are respectively fixedly connected to the bottom end of the slider 405 and the inner bottom wall of the slide groove 407; a connecting rod 401 hinged on one side of the slider 405; a shielding plate 403 symmetrically connected to the lower end of both sides of the protective box 3, and one side of the bottom end of the shielding plate 403 is hinged to one end of the connecting rod 401; a sponge block 402 fixedly connected to one side of the top of the shielding plate 403.

[0029] It should be noted that the existing hydraulic gate hoist protector still has certain shortcomings in actual use. There are no baffles on the front and back of the protector, which causes some rainwater to be blown from the front and back of the protective device to the hydraulic gate hoist due to factors such as strong winds when it rains, and there will also be strong sunlight shining on the hydraulic gate hoist, resulting in poor protection effect on it, and it is impossible to achieve more comprehensive shielding protection, which affects the service life of the hydraulic gate hoist.

[0030] In this embodiment, when it rains heavily, the sponge block 402 absorbs water and becomes heavier, thereby causing the shielding plate 403 to deflect downward, shielding the dust screen 6 and the ventilation hole 10 as much as possible, reducing the possibility of rainwater splashing into the ventilation hole 10 due to falling on the installation surface, and thus flowing into the protective box 3. When the rain stops, the rainwater inside the sponge block 402 will be evaporated. At this time, the elastic force of the return spring 406 is used to slide the slider 405 to drive the connecting rod 401 to deflect, thereby causing the shielding plate 403 to deflect upward and return to its original position, avoiding continuous blocking that affects the ventilation effect of the ventilation hole 10.

[0031] In a further preferred embodiment of the present invention, the length of the shielding plate 403 is greater than the distance between the ventilation holes 10 , and the downward deflection of the shielding plate 403 also effectively reduces the splashing of rainwater toward the ventilation holes 10 .

[0032] In a further preferred embodiment of the present invention, the upper ends of both sides of the protection box 3 are fixedly connected with rainproof plates 7, and the top end of the rainproof plates 7 is inclined at an angle of thirty degrees to the horizontal direction.

[0033] In this embodiment, the inclined rainproof plate 7 is used to prevent rainwater from dripping down from the rotation gap between the shielding plate 403 and the protection box 3.

[0034] In a further preferred embodiment of the present invention, dustproof nets 6 are fixedly connected to both sides of the protection box 3 by bolts, and the cross-sectional area of the dustproof net 6 is larger than the cross-sectional area formed between the ventilation holes 10.

[0035] In this embodiment, the dustproof net 6 can be used to shield the ventilation hole 10 from dust.

[0036] In a further preferred embodiment of the present invention, the ventilation holes 10 are inclined at an angle of sixty degrees to the vertical direction, and the ventilation holes 10 are symmetrically distributed at equal intervals on both sides of the protective box 3 .

[0037] In this embodiment, the inclined ventilation holes 10 are used so that even if a small amount of rainwater splashes into the interior, it will be discharged more quickly, reducing the possibility of entering the interior of the protective box 3. Example 2

[0038] On the basis of Example 1, the preferred embodiment of the protector for the hydraulic hoist provided by the present invention is as follows: Figures 1 to 5 As shown: a heating tube 11 is fixedly connected to the lower end of the inner wall of the protective box 3, a temperature and humidity sensor 12 is fixedly connected to the upper end of one side of the inner wall of the protective box 3, a controller 13 is fixedly connected to the upper end of the other side of the inner wall of the protective box 3, an exhaust hood 9 is fixedly connected to the upper end of the back side of the protective box 3, one end of the exhaust hood 9 is connected to the interior of the protective box 3, and a cooling fan 14 is fixedly connected to the inner wall of the exhaust hood 9.

[0039] In this embodiment, the temperature and humidity inside the protective box 3 are monitored by the temperature and humidity sensor 12. When the temperature is high, the cooling fan 14 can be started so that fresh air from the outside can be sucked in through the ventilation holes 10, and the heat inside the protective box 3 is discharged by the exhaust hood 9 to avoid excessive heat accumulation and affect the normal operation of the hydraulic gate opener. When the humidity is heavy or the temperature is too low, the heating tube 11 and the cooling fan 14 are started to generate heat inside the protective box 3, thereby effectively removing the moisture inside the protective box 3 and avoiding rust on the surface of the hydraulic gate opener caused by excessive humidity.

[0040] In a further preferred embodiment of the present invention, the heating tube 11 is serpentine in shape, and the heating tube 11 is symmetrically distributed about the vertical center axis of the protection box 3 .

[0041] In this embodiment, the serpentine heating tube 11 is used to increase the heating area and reduce the heating dead angle, so as to heat the interior of the protective box 3 more quickly.

[0042] In a further preferred embodiment of the present invention, a rain shield 8 is fixedly connected to the upper end of the back side of the protection box 3 , and the shape of the rain shield 8 is a right triangle.

[0043] In this embodiment, the right-angled triangle rain shield 8 is used to reduce the amount of rainwater that directly falls on the surface of the exhaust hood 9.

[0044] The working principle of this utility model is as follows: first, the protection box 3 is installed downward from the top of the hydraulic gate hoist, and then the protection box 3 is fixed to the installation surface by bolts. Then, a relatively closed space is formed by the protection box 3 and the door body 5, thereby reducing the adverse effects of rain or sunlight on the hydraulic gate hoist, and the top cover 1 will not hinder the rise or fall of the screw of the hydraulic gate hoist;

[0045] At the same time, when it rains heavily, the sponge block 402 absorbs water and becomes heavier, which causes the shielding plate 403 to deflect downward, driving the connecting rod 401 to deflect, so that the slider 405 slides on the surface of the slider 404 to compress the return spring 406, and then the downward deflected shielding plate 403 can block the dust screen 6 and the ventilation hole 10 as much as possible, reducing the possibility of rainwater splashing into the ventilation hole 10 due to falling on the installation surface, and thus flowing into the protection box 3. At the same time, the inclined ventilation hole 10 also makes it possible for even a small amount of rainwater to splash into it to be discharged faster, reducing the possibility of entering the protection box 3. Yes, and when the rain stops, the rainwater inside the sponge block 402 will evaporate. At this time, the elastic force of the return spring 406 causes the slider 405 to slide and drive the connecting rod 401 to deflect, thereby causing the shielding plate 403 to deflect upward and return to its original position, avoiding continuous blocking and affecting the ventilation effect of the vent 10. At the same time, due to the maximum sliding distance limit of the slider 405, the shielding plate 403 cannot be completely vertical, and thus, after the shielding plate 403 deflects downward to the maximum extent, there is still a certain gap between it and the dustproof net 6, thereby preventing the vent 10 from being unable to be fully ventilated due to complete blocking;

[0046] The temperature and humidity inside the protection box 3 can also be monitored by the temperature and humidity sensor 12. When the temperature is high, the cooling fan 14 can be started so that fresh air from the outside can be sucked in through the ventilation holes 10, and then the heat inside the protection box 3 can be discharged by the exhaust hood 9 to avoid excessive heat accumulation and affect the normal operation of the hydraulic gate opener. When the humidity is heavy or the temperature is too low, the heating pipe 11 and the cooling fan 14 are started to generate heat inside the protection box 3, thereby effectively removing the moisture inside the protection box 3 and avoiding rust on the surface of the hydraulic gate opener caused by excessive humidity. In addition, by setting the temperature and humidity sensor 12, excessive energy consumption caused by continuous operation of the heating pipe 11 or the cooling fan 14 can be avoided.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
