Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold storage plate lamp installation, and particularly relates to a cold storage plate lamp cold bridge prevention installation node and method. BACKGROUND

[0002] As a special storage space, the core feature of a cold storage is airtight or semi-airtight structure, which directly leads to the fact that natural light cannot enter the interior. However, daily operations such as cargo counting, loading and unloading, and equipment maintenance cannot be carried out without sufficient light support. If effective lighting is lacking, not only will the operation efficiency be reduced, but also safety accidents will be caused due to unclear vision. Therefore, artificial lighting must be provided for the interior of the cold storage, which requires installing lamps on the cold storage plate at the top of the cold storage.

[0003] To install lamps on the cold storage plate, the first step is to perform a hole opening operation. Because the lamps cannot be directly fixed on the surface of the complete cold storage plate, only by opening a hole can an installation channel be provided for the metal base of the lamp and the metal parts of the fixing screw, so that the lamp is stably attached to the cold storage plate, and then the lighting function is realized to meet the basic needs of daily operations of the cold storage. It can be said that the cold storage plate hole opening is the key link connecting the lighting demand and the lamp installation, and is a measure that must be taken to ensure the normal operation of the cold storage.

[0004] However, the traditional installation method of the cold storage plate lamp has the problems of cold bridge formation and cold loss. On the one hand, the metal base of the lamp and the metal parts of the fixing screw have high thermal conductivity, and when they directly pass through the installation hole and connect the low-temperature environment inside the cold storage with the normal-temperature environment outside the cold storage, a heat transfer channel is formed, which leads to the heat transfer into the interior of the cold storage and the cold loss to the outside, and finally a cold bridge is formed. On the other hand, it is difficult to ensure that the hole diameter and the lamp base are completely matched during the hole opening process, and the gap between them will become a channel for the exchange of cold and hot air, which not only aggravates the loss of cold, but also easily causes condensation and frosting problems.

[0025] Embodiments

[0026] As Figures 1 to 4As shown, the cold storage plate lamp fixture anti-cold bridge installation node provided by the application comprises a cold storage plate 1 and a lighting lamp 7. A mounting hole 11 is formed in the middle part of the cold storage plate 1. The mounting hole 11 serves as a basic carrier for lamp installation. A mounting hole 11 is formed thereon to provide an installation channel for the components of the conical cover 2 and the spiral rod 22, and to separate the low-temperature and normal-temperature environments inside and outside the cold storage. The conical cover 2 is arranged on the cold storage plate 1. The conical cover 2 is used for the deformed conical cover 2 to pass through, provides a space for the spiral rod 22 to penetrate the cold storage plate 1, and is a core hole position for connecting various installation components. The conical cover 2 is used to pass through the mounting hole 11 by being manually gripped and deformed. The material of the conical cover 2 is flexible polyurethane. Flexible polyurethane is a polyurethane material with high elasticity and flexibility, and belongs to a high polymer. The spiral rod 22 movably penetrates the mounting hole 11 and is fixedly connected in the conical cover 2. The spiral rod 22 can be spirally sleeved with the locking plate 3, the spiral cover 4 and the spiral sleeve 5. Through the spiral cooperation with various components, the fixing and positioning of various installation components are realized. At the same time, the locking force is transmitted to make the conical cover 2 abut against the cold storage plate 1. The outer wall of the spiral rod 22 clamped into the mounting hole 11 is fixedly connected with a plurality of limiting wing plates 23 arranged in a circumferential array. The limiting wing plates 23 are used to limit the displacement of the components of the spiral rod 22 and the locking plate 3 in the mounting hole 11, and ensure the stability of the installation structure. Polyurethane foaming agent is sprayed in the mounting hole 11 and the conical cover 2. The polyurethane foaming agent is a product that can generate foam through chemical reaction and finally solidify into a porous polyurethane material, and is mainly used for filling, sealing and heat preservation. The polyurethane foaming agent is used to expand and fill the inside of the mounting hole 11 and the conical cover 2. Polyurethane sealant 41 is sprayed in the spiral cover mechanism. The polyurethane sealant 41 is injected into the spiral cover 4 to fill the gap between the spiral cover 4, the spiral rod 22 and the locking plate 3. When the spiral cover 4 is sleeved and fixed, a sealing layer can be formed, and the sealing effect is enhanced by cooperating with the third sealing ring pad 42 to prevent cold and hot air from exchanging through the gap between the spiral cover 4 and other components. The polyurethane sealant 41 is an elastic sealing material with polyurethane as the main component, which is used for filling gaps, preventing medium leakage and playing a bonding role.

[0027] Among them, as Figures 2 to 4As shown, the end of the screw rod 22 away from the conical cover 2 is spirally sleeved with a blocking plate mechanism tightly against the outer wall of the cold storage plate 1, which includes a locking plate 3 spirally sleeved on the end of the screw rod 22, the locking plate 3 can be tightly against the outer wall of the cold storage plate 1 through the rotating lug plate 31, and then the conical cover 2 is synchronously tightly against through the screw rod 22; a material injection hole 32 is formed on the locking plate 3 for injecting polyurethane foaming agent, and preliminary sealing is realized through the cooperation of the second sealing ring pad 36 and the first sealing ring pad 24. The locking plate 3 is fixedly connected with a plurality of lug plates 31 distributed in a circumferential array, the lug plate 31 serves as a force point for rotating the locking plate 3, which facilitates the operator to rotate the locking plate 3 to move it on the screw rod 22 and tightly against the cold storage plate 1. After the locking plate 3 tightly against the cold storage plate 1, it is used to drive the conical cover 2 to tightly against the outer wall of the cold storage plate 1 through the screw rod 22, the locking plate 3 is provided with a material injection hole 32 in communication with the mounting hole 11, the material injection hole 32 is used for injecting polyurethane foaming agent into the mounting hole 11 and the conical cover 2, and is a key channel for filling the foaming agent; it is usually blocked and sealed by the guide plug 35. The inside of the material injection hole 32 is provided with a blocking mechanism.

[0028] In addition, as shown in the drawings, Figure 4 The blocking mechanism includes a guide plug 35 that penetrates the material injection hole 32 and blocks the locking plate 3, the guide plug 35 is removed when filling the foaming agent, and is installed back after filling is completed, the material injection hole 32 is sealed by the sealing block 34, and the position is fixed by the limiting clamping plate 33, to ensure that the foaming agent expands in the closed space. One end of the guide plug 35 is fixedly connected with a sealing block 34 tightly clamped into the material injection hole 32, and the sealing block 34 and the guide plug 35 are made of rubber material. The sealing block 34 can be tightly clamped into the material injection hole 32, and the sealing of the material injection hole 32 is realized by cooperating with the guide plug 35, to prevent the polyurethane foaming agent from overflowing from the material injection hole 32, and to ensure the normal expansion of the foaming agent in the mounting hole 11 and the conical cover 2. The end of the sealing block 34 away from the guide plug 35 is fixedly connected with a limiting clamping plate 33 clamping the locking plate 3, the limiting clamping plate 33 can clamp the outer wall of the locking plate 3 when the guide plug 35 penetrates the material injection hole 32, to prevent the guide plug 35 from falling off from the material injection hole 32, and to ensure the sealing effect when filling the foaming agent.

[0029] It is worth mentioning that, as shown in the drawings, Figures 1 to 4As shown, the second sealing ring pad 36 is fixedly connected to the side of the locking plate 3 away from the convex plate 31 and tightly abuts the outer wall of the cold storage plate 1. The second sealing ring pad 36 corresponds to the first sealing ring pad 24 on the conical cover 2. When the locking plate 3 abuts against the cold storage plate 1, it can tightly abut the outer wall of the cold storage plate 1, cooperate with the first sealing ring pad 24 to achieve preliminary sealing, and reduce the cold and heat exchange at the gap. The first sealing ring pad 24 is fixedly connected to the open end of the conical cover 2 and tightly abuts the cold storage plate 1 corresponding to the second sealing ring pad 36. When the conical cover 2 abuts against the cold storage plate 1, the first sealing ring pad 24 can tightly abut the outer wall of the cold storage plate 1, cooperate with the second sealing ring pad 36 to achieve preliminary sealing, and block the cold and heat exchange at the gap.

[0030] Further, as shown in the drawings, Figures 1 to 4 The conical cover 2 is provided with a plurality of circumferentially arrayed strip-shaped grooves 21. The strip-shaped grooves 21 provide deformation space for the conical cover 2, facilitate manual gripping of the cover body to reduce its size, and smoothly pass through the installation hole 11. The inside of the flexible polyurethane is inlaid with a plurality of steel bars that are circumferentially arrayed and correspond to the strip-shaped grooves 21. The steel bars are used to enhance the structural strength of the conical cover 2 when passing through the installation hole 11, avoid excessive deformation or damage of the conical cover 2 when it is deformed under stress and passes through the small-diameter installation hole 11, and ensure accurate recovery after passing through to ensure the sealing performance of the conical cover 2 abutting against the cold storage plate 1. In addition, the steel bars correspond to the strip-shaped grooves 21 in the same direction to ensure that the conical cover 2 is not blocked when it is deformed by hand. After filling the polyurethane foaming agent, the steel bars can disperse the pressure generated by the expansion of the foaming agent, the strip-shaped grooves 21 can flexibly adjust the shape, and the combination of the two can uniformly distribute the pressure to prevent the conical cover 2 from breaking or deforming excessively, maintain the accommodation and wrapping of the foaming agent, ensure the full expansion of the foaming agent to block the cold and heat exchange, and improve the cold bridge prevention performance.

[0031] Further, as shown in the drawings, Figures 1 to 3As shown, the spiral rod 22 is sleeved with a rotating cover mechanism that tightly covers the blocking plate mechanism at one end of the conical cover 2. The rotating cover mechanism includes a spiral cover 4 sleeved on the end of the spiral rod 22 to cover the locking plate 3. The inside of the spiral cover 4 can be injected with polyurethane sealant 41. The third sealing ring pad 42 is tightly pressed against the cold storage plate 1 to form a secondary seal and further block the heat exchange, while protecting the locking plate 3 and its internal components. The open end of the spiral cover 4 is fixedly connected with the third sealing ring pad 42 that tightly abuts against the outer wall of the cold storage plate 1. The third sealing ring pad 42 tightly abuts against the outer wall of the cold storage plate 1 when the spiral cover 4 is sleeved on the spiral rod 22, and cooperates with the polyurethane sealant 41 in the spiral cover 4 to achieve secondary sealing, further block the gap and reduce the loss of cold energy. After the third sealing ring pad 42 abuts against the outer wall of the cold storage plate 1, the polyurethane sealant 41 in the spiral cover 4 is allowed to overflow. The overflow of the sealant can directly determine whether the spiral cover 4 is filled with sealant and fully adheres to the contact surface, ensuring that the sealing effect meets the standard and preventing sealing failure due to insufficient sealant. The end of the spiral rod 22 close to the locking plate 3 and the spiral cover 4 is sleeved with a spiral sleeve seat 5. The spiral sleeve seat 5 is fixed by screwing with the spiral rod 22 to provide a mounting base for the mounting plate 6 and the lighting fixture 7, and transfers the weight of the lighting fixture to the spiral rod 22. The end of the spiral sleeve seat 5 away from the spiral cover 4 is fixedly connected with the mounting plate 6 for installing the lighting fixture 7. The mounting plate 6 serves as a mounting carrier for the lighting fixture 7, providing a fixed plane for the lighting fixture, facilitating the stable installation of the lighting fixture 7 on the spiral sleeve seat 5 and ensuring the position of the lighting fixture. The materials of the first sealing ring pad 24, the second sealing ring pad 36 and the third sealing ring pad 42 are fluorine rubber that is resistant to low temperature.

[0032] The present application provides a kind of cold storage plate lamp cold bridge installation node of anti- installation method, as shown in Figures 1 to 4 As shown, comprising the following steps: S1, set up mounting hole: drill mounting hole 11 in the middle of cold storage plate 1.

[0033] S2, set up conical cover: hold conical cover 2 with strip-shaped slot 21 and make it deform, after passing through mounting hole 11, conical cover 2 restores by material characteristics; S3, preliminary locking seal: the locking plate 3 is sleeved on the spiral rod 22 that penetrates mounting hole 11, rotates the lug plate 31 to make the locking plate 3 and the conical cover 2 respectively abut against the two sides of the cold storage plate 1, and the first sealing ring pad 24 cooperates with the second sealing ring pad 36 to realize preliminary sealing; S4, fill foaming agent: remove the guide plug 35, spray polyurethane foaming agent into mounting hole 11 and conical cover 2 through material injection hole 32, then put back the guide plug 35 and fix it by limiting clamping plate 33, so that the foaming agent expands to fill the block of heat exchange; S5, sleeve spiral cover sealing: polyurethane sealant 41 is injected into the spiral cover 4, which is sleeved on the spiral rod 22 to cover the locking plate 3, the third sealing ring pad 42 is tightly closed to the cold storage plate 1, and the overflow of the un-solidified polyurethane sealant 41 is cleaned up; S6, install the lamp: the spiral sleeve 5 is sleeved on the spiral rod 22, the lighting lamp 7 is installed by means of the mounting plate 6, and the displacement of the components is limited by the limiting wing plate 23, and the cold bridge prevention installation is completed.

[0034] In this embodiment, when the cold storage plate lamp cold bridge prevention installation node is used, the installation hole 11 is first formed in the middle of the cold storage plate 1, and then the tapered cover 2 is manually gripped. Because the tapered cover 2 is provided with a plurality of strip-shaped grooves 21, the tapered cover 2 will be deformed when it is gripped. The deformed tapered cover 2 can pass through the installation hole 11. Subsequently, the tapered cover 2 passing through the installation hole 11 quickly recovers to the original shape due to the material characteristics. And because the spiral rod 22 is movably penetrated through the installation hole 11 and fixed in the tapered cover 2, the locking plate 3 is sleeved on the end of the spiral rod 22 away from the tapered cover 2, and the convex plate 31 on the locking plate 3 is rotated, so that the locking plate 3 is tightly closed to the outer wall of the cold storage plate 1. At the same time, the tapered cover 2 is driven by the spiral rod 22 to be tightly closed to the outer wall of the cold storage plate 1, and the first sealing ring pad 24 at the open end of the tapered cover 2 corresponds to the second sealing ring pad 36 on the locking plate 3, and tightly abuts the cold storage plate 1 together, thereby preliminarily realizing sealing and leakage prevention.

[0035] Then, the guide plug 35 is removed, the polyurethane foaming agent is sprayed into the installation hole 11 and the inside of the tapered cover 2 through the material injection hole 32 on the locking plate 3, and after spraying, the guide plug 35 is movably penetrated through the material injection hole 32 and tightly clamped to the locking plate 3 by the sealing block 34. At this time, the limiting clamping plate 33 further fixes the guide plug 35, so as to ensure that the polyurethane foaming agent expands and fills the inside of the installation hole 11 and the tapered cover 2, thereby blocking the cold and heat exchange channel.

[0036] Then, the polyurethane sealant 41 is injected into the spiral cover 4, and is in the state as shown in Figure 2 Subsequently, the spiral cover 4 is sleeved on the end of the spiral rod 22 away from the tapered cover 2, so that the spiral cover 4 tightly covers the locking plate 3, and the third sealing ring pad 42 at the open end of the spiral cover 4 tightly abuts the outer wall of the cold storage plate 1. After abutting, the polyurethane sealant 41 in the spiral cover 4 will overflow, further enhancing the sealing and cold bridge prevention effect, and then the overflowed polyurethane sealant 41 which has not solidified is cleaned up. Finally, the spiral sleeve 5 is sleeved on the end of the spiral rod 22 close to the locking plate 3 and the spiral cover 4, and the lighting lamp 7 is installed by means of the mounting plate 6 on the spiral sleeve 5. At the same time, the limiting wing plate 23 on the spiral rod 22 can limit the displacement of each component, and finally the lamp installation is realized by the cooperation of multiple structures to prevent the cold bridge and the loss of cold quantity.
