Description

Technical Field

[0001] The utility model relates to the technical field of sensor installation, in particular to a mounting and supporting structure for a stress wave sensor. Background Art

[0002] During the operation of large-scale amusement facilities, they will bear various dynamic and static loads, which may cause fatigue, deformation and even potential damage to the structure. Stress wave sensors can detect stress wave signals propagating inside the facility structure. By analyzing these signals, key information about the health status of the facility structure can be obtained. For example, when a Ferris wheel rotates, key parts such as the axle, support and cabin connection parts will be subjected to constantly changing stresses. The accurate installation of stress wave sensors can monitor the changes in these stresses in real time and detect potential structural defects in advance, such as the initiation and propagation of metal fatigue cracks. Therefore, in the field of monitoring large-scale amusement facilities, the installation of stress wave sensors is crucial.

[0003] Currently, the mounting and supporting structures of stress wave sensors are usually combined with large-scale amusement facilities by means of bolt fastening, welding, gluing, magnetic adsorption, etc. Among them, the gluing method has become a common choice for installing stress wave sensors on many large-scale amusement facilities because of its relatively simple and fast operation, relatively low cost and less damage to the facility structure. However, the gluing method has obvious defects. Since the performance of the adhesive is significantly affected by temperature, in high-temperature weather, the adhesive is prone to softening, resulting in a significant reduction in the bonding strength; while in low-temperature environments, the adhesive may become brittle or even crack, seriously affecting the fixing effect of the sensor and unable to provide stable and reliable support for the safety monitoring of amusement facilities. Therefore, how to improve the mounting and supporting structure of stress wave sensors and overcome the disadvantages of the gluing method affected by temperature has become an urgent technical problem to be solved. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a mounting and supporting structure for a stress wave sensor to overcome or improve at least one technical problem of the prior art, or to provide a useful alternative.

[0005] To solve the above technical problems, the utility model has taken the following technical solutions:

[0006] A mounting and supporting structure for a stress wave sensor includes a sensor body, an adhesive layer is provided on the outer side of the sensor body, and a heat preservation component is provided outside the adhesive layer;

[0007] The thermal insulation component includes a protective shell. The adhesive layer is located inside the protective shell. The inner wall of the protective shell is provided with a thermal insulation cavity. Glass wool is arranged inside the thermal insulation cavity. Polyurethane foam is provided at the bottom of the glass wool. A plurality of electric heating sheets are arranged on the inner wall of the protective shell. The plurality of electric heating sheets are arranged in a ring shape and are located around the adhesive layer. The electric heating sheets can provide heat to keep the adhesive layer within a suitable temperature range in winter.

[0008] Through the above technical solution, the thermal insulation component prevents the adhesive layer from becoming brittle, losing adhesiveness or decreasing in adhesive strength due to low temperature, thereby ensuring the normal operation of the sensor body, improving the accuracy and stability of stress wave measurement, and providing reliable data support for the safety monitoring of large amusement facilities.

[0009] Furthermore, the protective shell is located outside the sensor body. Two springs are fixedly connected to the inner side of the protective shell. The opposite ends of the two springs are fixedly connected with a clamping ring.

[0010] Through the above technical solution, the protective shell is sleeved outside the sensor body. After the sensor body is installed in place, the two springs push the clamping ring to apply pressure to the sensor body, so that the sensor body is stably clamped between the two clamping rings, facilitating the replacement of the sensor body.

[0011] Furthermore, the sensor body is located between the two clamping rings, and the bottom of the sensor body is flush with the adhesive layer.

[0012] Through the above technical solution, the bottom of the sensor body is flush with the adhesive layer, enabling the sensor body to contact the object to be detected after installation. Direct contact with the object to be detected can more accurately obtain stress wave signals, reduce the attenuation and distortion of signals during propagation, and thus improve the detection accuracy and reliability.

[0013] Furthermore, a cooling pipe is arranged inside the protective shell. One end of the cooling pipe is communicated with a micro pump body, and the micro pump body is located inside the protective shell.

[0014] Furthermore, heat dissipation fins are arranged on the outer wall of the protective shell, and connecting pipes are communicated with both ends of the heat dissipation fins.

[0015] Furthermore, the connecting pipe penetrates and extends into the inside of the protective shell and is communicated with the cooling pipe.

[0016] Furthermore, heat dissipation fins are arranged on the outer wall of the protective shell, and connecting pipes are communicated with both ends of the heat dissipation fins. The connecting pipe penetrates and extends into the inside of the protective shell and is communicated with the cooling pipe.

[0017] Through the above technical solution, the heat sink and the micro pump body ensure that the bonding layer works at an appropriate temperature, preventing softening due to high temperature and reducing the bonding strength, thereby ensuring the firmness and stability of the installation of the sensor body. Moreover, it enables the stress wave sensor to work properly in hot summer or high-temperature working environments without being restricted by high-temperature conditions.

[0018] Furthermore, a heat insulation cavity is provided inside the protective housing. Asbestos is provided inside the heat insulation cavity, and ceramic fiber is provided at the bottom of the asbestos.

[0019] Through the above technical solution, the combination of asbestos and ceramic fiber greatly improves the heat insulation effect, reduces the influence of external high temperature on the inside of the protective housing, and particularly plays a good protective role for the bonding layer and the sensor body.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. Through the setting of the heat preservation component, in winter or low-temperature environments, the electric heating sheet on the inner wall of the protective housing is powered on to work, generating heat. The heat is transferred to the surrounding of the bonding layer, keeping it within an appropriate temperature range, preventing the bonding layer from becoming brittle, losing adhesiveness or reducing the bonding strength due to low temperature, thereby ensuring the normal operation of the sensor body, improving the accuracy and stability of stress wave measurement, and providing reliable data support for the safety monitoring of large amusement facilities;

[0022] 2. Through the setting of the heat sink and the micro pump body, it ensures that the bonding layer works at an appropriate temperature, preventing the bonding layer from softening and reducing the bonding strength due to high temperature in hot summer, thereby ensuring the firmness and stability of the installation of the sensor body.

Specific embodiments

[0031] The technical solution of the present utility model will be further described below with reference to the drawings and embodiments.

[0032] Embodiment 1

[0033] Refer to Figures 1-4 , a stress wave sensor installation and support structure, including a sensor body 1, an adhesive layer 3 is provided outside the sensor body 1, and a heat preservation component is provided outside the adhesive layer 3;

[0034] The heat preservation component includes a protective housing 2. The adhesive layer 3 is located inside the protective housing 2. A heat preservation cavity is provided on the inner wall of the protective housing 2. Glass wool 9 is provided inside the heat preservation cavity. Polyurethane foam 8 is provided at the bottom of the glass wool 9. A plurality of electric heating sheets 6 are provided on the inner wall of the protective housing 2. The plurality of electric heating sheets 6 are arranged in a ring shape and are located around the adhesive layer 3. The electric heating sheets 6 can provide heat to keep the adhesive layer 3 within a suitable temperature range in winter.

[0035] When the sensor body 1 is installed at a corresponding position of a large amusement facility, the sensor body 1 is adhesively fixed through the outer adhesive layer 3. The protective housing 2 is wrapped outside the adhesive layer 3 to play a protective role. In winter or low-temperature environments, the electric heating sheets 6 on the inner wall of the protective housing 2 are powered on to generate heat. The heat is transferred to the surrounding of the adhesive layer 3 to keep it within a suitable temperature range, preventing the adhesive layer 3 from becoming brittle, losing adhesiveness or decreasing adhesive strength due to low temperature. At the same time, the glass wool 9 and polyurethane foam 8 inside the heat preservation cavity can effectively reduce heat dissipation, enhance the heat preservation effect, and further maintain the stability of the temperature around the adhesive layer 3.

[0036] Through the synergistic effect of the electric heating sheets 6 and the heat preservation materials (glass wool 9 and polyurethane foam 8), the adhesive layer 3 maintains good performance in low-temperature environments, ensuring the firmness and reliability of the installation of the sensor body 1, reducing the risk of adhesive failure caused by low temperature, thereby ensuring the normal operation of the sensor body 1, improving the accuracy and stability of stress wave measurement, and providing reliable data support for the safety monitoring of large amusement facilities.

[0037] It can also enable the installation and support structure of the sensor body 1 to work normally under a wider range of temperature conditions, especially suitable for cold regions or seasons.

[0038] Reference Figures 3-4 As shown in Figures 3-4 , the protective housing 2 is located outside the sensor body 1. Two springs 4 are fixedly connected to the inner side of the protective housing 2. The opposite ends of the two springs 4 are fixedly connected with a clamping ring 5. The sensor body 1 is located between the two clamping rings 5, and the bottom of the sensor body 1 is flush with the adhesive layer 3.

[0039] The protective housing 2 is sleeved outside the sensor body 1. After the sensor body 1 is installed in place, the two springs 4 push the clamping ring 5 to apply pressure to the sensor body 1, so that the sensor body 1 is stably clamped between the two clamping rings 5, facilitating the replacement of the sensor body 1.

[0040] The bottom of the sensor body 1 is flush with the adhesive layer 3, enabling the sensor body 1 to contact the object to be detected after installation. Direct contact with the object to be detected can more accurately obtain stress wave signals, reduce attenuation and distortion of the signals during propagation, thereby improving the accuracy and reliability of detection.

[0041] Embodiment 2

[0042] Reference Figures 5-7 As shown in Figures 5-7 , a cooling pipe 14 is provided inside the protective housing 2. One end of the cooling pipe 14 is communicated with a micro pump body 13. The micro pump body 13 is located inside the protective housing 2. Heat dissipation fins 12 are provided on the outer wall of the protective housing 2. Both ends of the heat dissipation fins 12 are communicated with a connecting pipe 11. The connecting pipe 11 penetrates and extends into the protective housing 2 and is communicated with the cooling pipe 14. An insulating cavity is provided inside the protective housing 2, and asbestos 7 is provided inside the insulating cavity. Ceramic fiber 10 is provided at the bottom of the asbestos 7.

[0043] In summer or high-temperature environments, the temperature inside the protective housing 2 rises. At this time, the micro pump body 13 works to drive the coolant in the cooling pipe 14 to flow. The coolant absorbs heat during the flow process, and then flows to the heat dissipation fins 12 through the connecting pipe 11. The heat dissipation fins 12 have a large contact area with the outside air and can quickly dissipate the heat in the coolant to the surrounding environment. The cooled coolant then returns to the cooling pipe 14 through the connecting pipe 11 to continue circulating and absorbing heat, thereby continuously cooling the adhesive layer 3 inside the protective housing 2.

[0044] Ensure that the adhesive layer 3 works at an appropriate temperature, prevent softening due to high temperature and reduce the bonding strength, thereby ensuring the firmness and stability of the installation of the sensor body 1, and also enabling the stress wave sensor to work normally in hot summer or high-temperature working environments without being restricted by high-temperature conditions.

[0045] The combination of asbestos 7 and ceramic fiber 10 greatly improves the heat insulation effect, reduces the influence of external high temperature on the inside of the protective housing 2, and especially plays a good protective role for the adhesive layer 3.

[0046] Working principle: First, the protective housing 2 is sleeved outside the sensor body 1. After the sensor body 1 is installed in place, two springs 4 push the clamping ring 5 to apply pressure to the sensor body 1, so that the sensor body 1 is stably clamped between the two clamping rings 5. Subsequently, the sensor body 1 is installed at the position where stress needs to be detected through the adhesive layer 3. Since the bottom of the sensor body 1 is flush with the adhesive layer 3, the sensor body 1 can contact the object to be detected after installation, thereby obtaining stress wave signals. The protective housing 2 is wrapped outside the adhesive layer 3 for protection. In winter or low-temperature environments, the electric heating sheet 6 on the inner wall of the protective housing 2 is energized to generate heat, and the heat is transferred to the surroundings of the adhesive layer 3. At the same time, the glass wool 9 and polyurethane foam 8 inside the heat preservation cavity reduce heat dissipation, enhance the heat preservation effect, keep the adhesive layer 3 at an appropriate temperature, prevent it from becoming brittle due to low temperature, losing viscosity or decreasing adhesive strength, and ensure the firmness and reliability of the installation of the sensor body 1.

[0047] In summer or high-temperature environments, the temperature inside the protective housing 2 rises. At this time, the micro pump body 13 works to drive the coolant in the cooling pipe 14 to flow. The coolant absorbs heat during the flow process, and then flows through the connecting pipe 11 to the heat sink 12. The heat sink 12 has a large contact area with the outside air and can quickly dissipate the heat in the coolant to the surrounding environment. The cooled coolant then returns to the cooling pipe 14 through the connecting pipe 11 to continue circulating and absorbing heat, thereby continuously cooling the adhesive layer 3 inside the protective housing 2.

[0048] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the scope of the technical solution of the present invention.
