Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration units, and more specifically, it relates to an anti-collision protection device. Background Art

[0002] A refrigeration unit is a device used to achieve the conversion of thermal energy and provide cold air for cold chain or air conditioning. It operates under large temperature and pressure change ranges and high rotational speeds, and is usually installed outdoors. Therefore, in order to reduce the vibration friction of the unit itself and external impacts, the refrigeration unit is usually fixedly installed on the ground and provided with a protection device.

[0003] The Chinese utility model patent with the application number 202323004166.4 discloses an anti-collision protection device for a refrigeration unit. Guardrails are provided on the top surface and four side surfaces of the refrigeration unit. The guardrails can protect the refrigeration unit from the impact of external objects, but increase the installation volume, consume more materials, and have a high installation cost. Moreover, the guardrails are also fixed to the ground by ground nails. When subjected to a large impact, the impact is transmitted between the connection surfaces to generate shear force and easily break the bolts. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an anti-collision protection device for a refrigeration unit that is not easily damaged.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-collision protection device includes a base, on which an outer shell and several fixing rods are fixed. Several of the fixing rods are all arranged inside the outer shell, and a top cover is fixedly connected to the several fixing rods together. The top cover is movably connected to the outer shell. The base is connected to the ground through anchor bolts, and guardrails are provided on the outer side surfaces of the outer shell.

[0007] The utility model is further provided as: The anchor bolt includes a bolt body and a spherical buffer pad. The bolt body penetrates through the base and the spherical buffer pad and is threadedly connected to the ground. The contact surface between the base and the ground is the connection surface, and the connection surface and the central plane of the spherical buffer pad are in the same plane.

[0008] The utility model is further provided as: The spherical buffer pad is a rubber ball.

[0009] The utility model is further provided as: The top end of the outer shell is a connection end, the cross-section of the connection end is "concave", a rubber sleeve is fitted in the groove of the connection end, the rubber sleeve is in the shape of "concave", and installation eaves are vertically arranged at the edges of the top cover, and the installation eaves are connected to the groove of the rubber sleeve.

[0010] The present utility model is further configured as follows: The guardrail includes a plurality of hoisting rods, and a baffle is slidably connected to the plurality of hoisting rods. A plurality of springs are evenly installed on the baffle, and the other ends of the springs are fixed to the outer shell.

[0011] The present utility model is further configured as follows: A buffer pad is attached to the side of the baffle facing away from the outer shell, and the buffer pad is made of an elastic material.

[0012] The advantages of the present utility model are as follows:

[0013] 1. The refrigeration unit is fixedly installed on the ground through anchor bolts. The bolt body penetrates through the spherical buffer pad and is connected to the ground. The central plane of the spherical buffer pad coincides with the ground surface. When the outer shell is strongly impacted, the base squeezes the spherical buffer pad through the bolt body, and the impact force on the bolt body is dispersed into multi-directional forces through the spherical structure, preventing the connecting surface from generating shear force on the bolt body due to the impact and avoiding damage to the anchor bolts.

[0014] 2. The top cover and the outer shell are set as a split structure. The top cover is fixed to the base through fixing rods, and the top cover and the outer shell are connected by a rubber sleeve. When the outer shell is impacted, its vibration is alleviated by the rubber sleeve and is not directly transmitted to the top cover, avoiding resonance of the internal structure of the refrigeration unit driven by the top cover and reducing wear of the internal structure.

[0015] 3. Guardrails are provided on all sides of the outer shell, and buffer pads are provided on the outer side of the baffle of the guardrail. When the guardrail is impacted, the impact is dispersed by the buffer pads and the springs, reducing damage to the refrigeration unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail the present invention.

[0023] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0024] In the present invention, without contrary description, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides the following technical solutions:

[0026] An anti-collision protection device, including a base 2, an outer shell 1 and a plurality of fixed rods 6 are fixed on the base 2, the plurality of fixed rods 6 are all arranged inside the outer shell 1, a top cover 3 is fixedly connected together on the plurality of fixed rods 6, the top cover 3 is movably connected to the outer shell 1, when the outer shell 1 is impacted, the impact force is hardly transmitted to the top cover 3, thereby reducing the vibration of the top cover 3 and reducing the vibration wear of the internal structure of the refrigeration unit;

[0027] The base 2 is connected to the ground through anchor bolts 5. When the refrigeration unit is impacted greatly, the anchor bolts 5 disperse the impact force, avoiding the shear force on the connection surface from breaking the bolts;

[0028] Guardrails 4 are arranged on the outer side surfaces of the outer shell 1, which can buffer the impact.

[0029] The anchor bolt 5 includes a bolt body 51 and a spherical buffer pad 52. The bolt body 51 penetrates through the base 2 and the spherical buffer pad 52 and is threadedly connected to the ground. The contact surface between the base 2 and the ground is the connection surface, and the connection surface and the central plane of the spherical buffer pad 52 are in the same plane. The spherical buffer pad 52 is a rubber ball. When the outer shell 1 is subjected to a large impact, the ground pulls the base 2 through the anchor bolt 5 to prevent the refrigeration unit from shifting, thereby generating a large shear force on the connection surface. The shear force acts on the spherical buffer pad 52, and the spherical structure of the spherical buffer pad 52 can decompose the shear force into forces in multiple directions, thereby dispersing the magnitude of the unidirectional force and avoiding the breakage of the bolt body 51. At the same time, the elastic material of the spherical buffer pad 52 can provide a certain buffer for the shear force, thereby realizing the protection of the bolt body 51.

[0030] The top end of the outer shell 1 is a connection end 11. The cross-section of the connection end 11 is "concave". A rubber sleeve 12 is fitted in the groove of the connection end 11. The rubber sleeve 12 is "concave". Installation eaves 31 are vertically provided at the edges of the top cover 3. The installation eaves 31 are connected to the groove of the rubber sleeve 12. When the outer shell 1 is impacted and vibrates, the impact force is buffered by the rubber sleeve 12 when it is transmitted to the connection end 11, thereby reducing the magnitude of the force transmitted to the top cover 3. The internal structure of the refrigeration unit is usually fixed by the base 2 and the top cover 3 together. When the vibration of the top cover 3 decreases, the vibration of its internal structure also decreases, thereby reducing wear.

[0031] The guardrail 4 includes a number of lifting rods 41. A baffle 43 is slidably connected to the number of lifting rods 41. A number of springs 42 are evenly installed on the baffle 43. The other ends of the springs 42 are fixed to the outer shell 1. When the baffle 43 is impacted, part of the impact force is offset by the elastic force of the springs 42, thereby realizing impact buffering. A buffer pad 44 is fitted on the side of the baffle 43 facing away from the outer shell 1. The buffer pad 44 is made of an elastic material and can avoid the direct impact of external forces on the baffle 43 and prevent the baffle 43 from being damaged.

[0032] Specifically, the refrigeration unit is fixedly installed on the ground through the anchor bolt 5. The bolt body 51 penetrates through the spherical buffer pad 52 and is connected to the ground. The central plane of the spherical buffer pad 52 coincides with the ground surface. When the outer shell 1 is subjected to a strong impact, the base 2 squeezes the spherical buffer pad 52 through the bolt body 51, and the impact force on the bolt body 51 is dispersed into forces in multiple directions through the spherical structure, preventing the impact from generating a shear force on the bolt body 51 by the connection surface and avoiding the damage of the anchor bolt 5.

[0033] The top cover 3 and the outer shell 1 are set as a split structure. The top cover 3 is fixed on the base 2 through the fixing rod 6. The top cover 3 and the outer shell 1 are connected by a rubber sleeve 12. When the outer shell 1 is impacted, its vibration is relieved by the rubber sleeve 12 and is not directly transmitted to the top cover 3, avoiding the resonance of the internal structure of the refrigeration unit driven by the top cover 3 and reducing the wear of the internal structure.

[0034] Guardrails 4 are provided around the outer shell 1. A buffer pad 44 is provided on the outer side of the baffle 43 of the guardrail 4. When the guardrail 4 is impacted, its impact is dispersed by the buffer pad 44 and the spring 42, reducing the damage to the refrigeration unit.
