Description

Technical Field

[0001] This application relates to the field of building energy conservation construction testing, and in particular to a building energy conservation testing device and method. Background Technology

[0002] During the construction process, it is necessary to conduct multi-dimensional inspections on the building walls. One important inspection is the verticality of the walls, which ensures that the constructed walls are perpendicular to the ground, thereby ensuring the stability of the building walls.

[0003] Currently, the verticality of walls is typically tested using lasers, plumb bobs, or spirit levels, and the principles are largely the same. For example, when using a laser, the construction workers first place the laser emitter on one side of the bottom of the wall, then turn it on. The laser emitter emits a beam of light, and the construction workers calculate whether the wall is vertical by observing the horizontal distance between the beam and the wall. However, construction workers usually conduct the test after the wall has been built. If the test reveals that the wall is tilted, part of the wall needs to be demolished, resulting in a significant waste of resources. Summary of the Invention

[0004] In order to facilitate construction workers to detect the verticality of the walls in real time during the construction process, and to prevent the situation where the walls are found to be tilted after completion, requiring the demolition of parts of the walls and causing a large waste of resources, this application provides a building energy conservation detection device and method.

[0005] This application provides a building energy efficiency testing device and method, which adopts the following technical solution:

[0006] In a first aspect, this application provides a building energy efficiency testing device, comprising a base, mounting plates arranged parallel and spaced above the base, connecting columns fixed between the base and the mounting plates, two protective plates arranged parallel and spaced on the top of the mounting plates, mounting columns hinged to the two protective plates on their adjacent sides, a laser emitter disposed within the mounting columns, a fixing mechanism disposed between the mounting columns and the protective plates for fixing the mounting columns to the protective plates in a direction perpendicular to or parallel to the mounting plates, and a leveling mechanism disposed on the base for leveling the base.

[0007] The mounting post has a mounting groove along its length, and the laser emitter is inserted into the mounting groove. The two protective plates and the mounting plate form a protective cavity, and the mounting post and the laser emitter can be rotated into the protective cavity.

[0008] By adopting the above technical solution, during the wall construction process, the construction workers first place the monitoring device on the ground near the masonry wall. Then, they adjust the base to a horizontal position using the leveling mechanism. Next, they operate the fixing mechanism to release the mounting column from the protective plate, rotate the mounting column to a vertical position, and then the mounting column drives the laser emitter to a vertical position. The fixing mechanism then secures the mounting column to the protective plate. Finally, they turn on the laser emitter, allowing the detection device to start quickly during construction. The construction workers then build the wall along the light beam, observing the horizontal distance between the light beam and the wall in real time. The two protective plates and the mounting plate together... The system forms a protective cavity, allowing the mounting column and laser emitter to be rotated into the cavity for storage when not in use. The mounting column is then fixed to the protective plate by a fixing mechanism, thus protecting the laser emitter and extending its lifespan. The leveling mechanism supports the mounting plate and keeps it horizontal. During wall construction, workers can monitor the wall's verticality in real time, preventing the need for partial demolition after completion due to wall tilt. This improves resource utilization and shortens the construction period.

[0009] Optionally, the fixing mechanism includes a drive rod rotatably connected to one side of the mounting column, a cam fixedly sleeved on the drive rod, a control block slidably connected inside the mounting column along the length of the mounting column, a first spring fixed on the control block away from the cam, and a plurality of plug-in rods slidably connected to the control block.

[0010] The control block abuts against the cam, and a connecting groove is provided in the mounting column along the length of the mounting column. The control block moves within the connecting groove, and the other end of the first spring is fixedly connected to the inner wall of the connecting groove. The first spring is always in a compressed state.

[0011] The control block is perpendicular to the plug rod, and the connection between the control block and the plug rod is set with mutually abutting inclined surfaces. The mounting post has a plug hole adapted to the plug rod. The plug rod slides in the corresponding plug hole. The protective plate has multiple first plug slots and multiple second plug slots. The multiple first plug slots, multiple second plug slots and multiple plug rods correspond one-to-one. One end of the plug rod can pass through the plug hole and be inserted into the first plug slot or the second plug slot.

[0012] By adopting the above technical solution, when the construction personnel operate the fixing mechanism to fix the mounting column perpendicularly to the mounting plate on the protective plate, they first rotate the drive rod. The drive rod drives the cam to rotate, and the far hub of the cam drives the control block to move downward. The first spring is further compressed. Since the first spring is always in a compressed state, it always provides a force close to the cam to the control block, so that the control block and the cam are always in close contact. The control block can then drive the insertion rod to move towards the protective plate, so that one end of the insertion rod passes through the insertion hole and is inserted into the first insertion slot, thereby fixing the mounting column. Conversely, when the construction personnel release the fixing mechanism, they first rotate the drive rod in the opposite direction, so that the near hub of the cam and the control block are in close contact. When the control block abuts, it moves closer to the cam under the elastic force of the first spring. At the same time, the control block drives one end of multiple plug rods to move out of the first plug groove and retract into the plug hole, thereby releasing the fixing of the mounting column. Similarly, when the mounting column rotates to be parallel to the protective plate, the above operation is repeated so that one end of the plug rod passes through the plug hole and is inserted into the second plug groove, thus fixing the mounting column. The fixing mechanism allows the construction personnel to fix the mounting column on the protective plate in a direction perpendicular to the mounting plate, and also to fix the mounting column on the protective plate in a direction parallel to the protective plate, thus fixing the mounting column and the protective plate in two relative positions, which is convenient for construction personnel to operate.

[0013] Optionally, a limiting component for limiting the rotation angle of the drive rod is also provided between the drive rod and the mounting post.

[0014] By adopting the above technical solution, the limiting component can limit the rotation angle of the drive rod, making it easier for construction personnel to control the contact between the near or far hub of the cam and the control block, thereby facilitating the control of one end of the plug rod to be inserted into or removed from the first or second plug slot.

[0015] Optionally, the limiting assembly includes a drive wheel fixed to one end of the drive rod, a first limiting post fixed to the drive wheel near the drive rod, and two second limiting posts fixed to the mounting posts.

[0016] The first limiting post is located between the two second limiting posts. A first limiting groove is provided on the side wall of the mounting post. The first limiting groove is a recessed groove. The drive wheel rotates within the first limiting groove. The two second limiting posts are arranged symmetrically along the radial direction of the drive wheel.

[0017] By adopting the above technical solution, when the construction worker rotates the drive wheel, and the first limiting post abuts against one of the second limiting posts, the far hub of the cam moves closer to the control block, so that one end of the plug rod is inserted into the first or second plug groove. When the drive wheel is rotated in the opposite direction, and the first limiting post abuts against the other second limiting post, one end of the plug rod disengages from the first or second plug groove and retracts into the mounting post. At the same time, the first limiting groove is a recessed groove, which makes it less likely for the drive wheel to interfere with the wall.

[0018] Optionally, the plug rod has a chamfer on the side near the protective plate.

[0019] By adopting the above technical solution, the chamfer serves as a guide when the end of the connector rod is inserted into the first or second connector groove, and also makes it less likely for the connector rod to get stuck in the first or second connector groove, thus making it smoother for the connector rod to be inserted into or removed from the first or second connector groove.

[0020] Optionally, the leveling mechanism includes multiple screws threadedly connected to the base and a control component disposed between the screws and the base for controlling the rotation of the screws.

[0021] By adopting the above technical solution, when adjusting the base to a horizontal state through the leveling mechanism, the construction personnel first drive the screw to rotate through the control component. The screw moves away from or closer to the base, thereby raising or lowering one side of the base. Then, the multiple screws are adjusted to adjust the base and mounting plate to a horizontal state. The control component makes it easy for the construction personnel to operate the screw rotation, thus making the leveling process simpler and more convenient.

[0022] Optionally, the control component includes multiple knobs disposed above the base and corresponding to multiple screws, multiple control rods fixed below the knobs, a limiting block fixed on the side of the control rod away from the central axis of the knob, a connecting ring fixed above the screw, and a second spring disposed between the connecting ring and the corresponding knob.

[0023] The connecting ring has multiple control slots that are adapted to the control lever. The end of the control lever away from the knob can be inserted into the control slot. The base also has a second limiting slot. The limiting block and the connecting ring can slide and rotate within the second limiting slot. The second spring always applies a force away from the screw to the knob.

[0024] By adopting the above technical solution, when the screw is rotated by the control component, the operator first presses the knob downwards. The knob moves the control rod downwards and inserts it into the control slot, thus connecting the knob and the screw. At the same time, the second spring is further compressed. Then, the operator rotates the knob, which drives the screw to rotate. After the operator has finished adjusting, the knob is released, and the knob will automatically spring upwards under the action of the second spring. Therefore, even if the knob is accidentally touched, it is not easy for the knob to drive the screw to rotate, thereby improving the stability of the leveling mechanism.

[0025] Optionally, the number of the second springs is set to multiple, and the multiple second springs are evenly distributed along the circumference of the knob, and the two ends of the second springs are fixedly connected to the knob and the connecting ring respectively.

[0026] By adopting the above technical solution, multiple second springs ensure that the knob is subjected to uniform force along its circumference. At the same time, the uniform spacing makes it difficult for the knob to rotate after being accidentally touched. Furthermore, the two ends of the second springs are fixedly connected to the knob and the connecting ring, respectively, so that even if the knob is accidentally touched and rotated, it can quickly return to the initial position. This prevents the control lever and control groove from becoming misaligned, thus facilitating operation by subsequent construction personnel.

[0027] Optionally, a spirit level is also provided above the base.

[0028] By adopting the above technical solution, the leveling bubble makes the horizontal state of the base visible, eliminating the need for construction personnel to judge whether the base is level based on experience, and making it convenient for construction personnel to level the base.

[0029] Secondly, this application also provides a building energy efficiency testing method, applicable to one of the aforementioned building energy efficiency testing devices, the construction steps of which are as follows:

[0030] S1. Clean the ground on one side of the wall to be built and place the base on the ground;

[0031] S2. Use the fixing mechanism to release the mounting column from the protective plate, rotate the mounting column so that the mounting column and the laser emitter are perpendicular to the mounting plate, and use the fixing mechanism again to fix the mounting column to the protective plate.

[0032] S3. Next, the mounting column is abutted against one side of the wall, and the base is leveled using the leveling mechanism.

[0033] S4. Turn on the laser emitter. Construction workers build the wall along the beam emitted by the laser emitter and observe the horizontal distance between the beam and the wall in real time.

[0034] S5. During non-construction periods, the construction personnel should rotate the mounting column and laser emitter into the protective cavity for storage, and fix the mounting column to the protective plate using the fixing mechanism to protect the laser emitter. During construction, the construction personnel should repeat the above steps S2-S4 to achieve rapid start-up of the detection device.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. The leveling mechanism can support the mounting plate and keep it level. At the same time, during the construction of the wall, the construction personnel can check the verticality of the wall in real time, so that it is less likely that the wall will be found to be tilted after it is built, and the part of the wall will need to be demolished. This improves resource utilization and shortens the construction cycle of building the wall.

[0037] 2. The fixing mechanism allows construction workers to fix the installation column on the protective plate in a direction perpendicular to the installation plate, and also to fix the installation column on the protective plate in a direction parallel to the protective plate. This achieves the fixing of the installation column and the protective plate in two relative positions, which is convenient for construction workers to operate.

[0038] 3. The limiting component can limit the rotation angle of the drive rod, making it easier for construction personnel to control the contact between the near or far hub of the cam and the control block, thereby facilitating the control of one end of the plug rod to insert into or move out of the first or second plug slot.

[0039] 4. The control components make it easy for construction personnel to operate the screw rotation, making leveling simpler and more convenient; and after the construction personnel have finished adjusting, they can release the knob, which will automatically spring upward under the action of the second spring, so even if the knob is accidentally touched, it will not easily drive the screw to rotate, thereby improving the stability of the leveling mechanism.

[0040] 5. Multiple second springs ensure that the knob is evenly stressed along its circumference. Their even spacing also prevents the knob from turning accidentally. Furthermore, the two ends of the second springs are fixedly connected to the knob and the connecting ring, respectively, so that even if the knob is turned accidentally, it can quickly return to its initial position. This prevents the control lever and control slot from becoming misaligned, thus facilitating operation by subsequent construction personnel. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0048] This application discloses a building energy efficiency testing device and method. (Refer to...) Figure 1 and Figure 2 The monitoring device includes a base 1, with mounting plates 2 arranged parallel and spaced apart on top of the base 1. A connecting column 3 is fixed between the base 1 and the mounting plate 2. Two protective plates 4 are fixed on the top of the mounting plate 2, arranged horizontally, parallel and spaced apart, forming a protective cavity with the mounting plate 2. A mounting column 5 is hinged to one side of the two protective plates 4, and a laser emitter 6 is installed inside the mounting column 5. A mounting groove 51 is formed along the length of the mounting column 5, and the laser emitter 6 is located in the mounting groove 51. A rubber layer is laid on the inner wall of the mounting groove 51, which has good cushioning and shock absorption effects, making it less likely for the laser emitter 6 to shake after vibration. At the same time, the mounting column 5 and the laser emitter 6 can rotate into the protective cavity. A fixing mechanism 7 is provided between the mounting column 5 and the protective plate 4, which is used to fix the mounting column 5 to the protective plate 4 in a direction perpendicular to the mounting plate 2 or parallel to the protective plate 4. The base 1 is equipped with a leveling mechanism 8, which is used to level the base 1.

[0049] During the wall construction process, the construction workers first place the monitoring device on the ground near the masonry wall. Then, they operate the fixing mechanism 7 to release the fixing of the mounting column 5 and the protective plate 4, and rotate the mounting column 5 to make the mounting column 5 and the laser emitter 6 vertical. Then, they fix the mounting column 5 to the protective plate 4 again using the fixing mechanism 7. Next, the construction workers operate the leveling mechanism 8 to adjust the base 1 to a horizontal state. Finally, they turn on the laser emitter 6, and the construction workers stack the wall along the light column, observing the horizontal distance between the light column and the wall in real time. When the construction workers are not working, the mounting column 5 and the laser emitter 6 can be rotated into the protective cavity for storage, and the mounting column 5 and the protective plate 4 can be fixed by the fixing mechanism 7 to protect the laser emitter 6.

[0050] Reference Figure 2 and Figure 3 The fixing mechanism 7 includes a drive rod 71 rotatably connected to one side of the mounting post 5. A cam 72 is fixedly sleeved on the drive rod 71. A control block 73 is slidably connected inside the mounting post 5 along its length. A connecting groove 52 is provided inside the mounting post 5, and the control block 73 slides within the connecting groove 52. A first spring 74 is fixedly mounted on the control block 73 on the side away from the cam 72. The other end of the first spring 74 is fixedly connected to the mounting post 5, and the first spring 74 is always in a compressed state, thereby always providing the control block 73 with a force close to the cam 72, so that the convex control block 73 and the cam 72 are in tight contact. Multiple plug-in rods 75 are slidably connected to the control block 73, preferably two. The control block 73 and the two plug-in rods 75 are perpendicular to each other and the two plug-in rods 75 are symmetrically arranged. The connection points between the two plug-in rods 75 and the control block 73 are both inclined surfaces that abut against each other. Dovetail blocks 76 are fixed on the side of the two plug-in rods 75 near the connection point between the plug-in rod 75 and the control block 73. The control block 73 has a dovetail groove that matches the dovetail block 76. The dovetail block 76 slides in the dovetail groove. The dovetail block 76 is used to prevent the plug-in rods 75 from easily disengaging from the control block 73, and to drive the plug-in rods 75 to move closer to or away from the protection plate 4.

[0051] Reference Figure 3 and Figure 4 The mounting post 5 has insertion holes 53 adapted to the insertion rods 75, and the protective plate 4 has two first insertion slots 41 and two second insertion slots 42. The two first insertion slots 41, two second insertion slots 42, and two insertion rods 75 correspond one-to-one. One end of the insertion rod 75 can pass through the insertion hole 53 and be inserted into the first insertion slot 41 or the second insertion slot 42. The two insertion rods 75 have chamfered edges on the side near the protective plate 4, which makes it easier for the insertion rods 75 to enter or exit the first insertion slot 41 or the second insertion slot 42. A limit assembly 77 is also provided between the drive rod 71 and the mounting post 5 to limit the rotation angle of the drive rod 71.

[0052] Reference Figure 3 and Figure 4 The limiting assembly 77 includes a drive wheel 771 fixed to one end of the drive rod 71. A first limiting groove 54 is provided on the side wall of the mounting column 5. The first limiting groove 54 is a recessed groove, which is used to prevent the drive wheel 771 from interfering with the wall. The drive wheel 771 rotates within the first limiting groove 54. A first limiting post 772 is fixed on the drive wheel 771 near the drive rod 71. Two second limiting posts 773 are fixed on the mounting column 5. The two second limiting posts 773 are symmetrically arranged radially along the drive wheel 771. The first limiting post 772 is located between the two second limiting posts 773, and the first limiting post 772 and the two second limiting posts 773 are within the same circumference.

[0053] When the construction personnel operate the fixing mechanism 7 to fix the mounting column 5 perpendicular to the mounting plate 2, they first rotate the drive wheel 771. The drive wheel 771 drives the drive rod 71 to rotate, which in turn drives the cam 72 to rotate. At the same time, the first limiting post 772 on the drive wheel 771 abuts against one of the second limiting posts 773, causing the hub of the cam 72 to abut against the control block 73. The cam 72 drives the control block 73 to move away from the cam 72, and the control block 73 drives the insertion rod 75 to move closer to the protective plate 4, so that one end of the insertion rod 75 passes through the insertion hole 53 and is located in the first insertion groove 41, thus fixing the mounting column 5 perpendicular to the mounting plate 2. Conversely, the construction personnel release the mounting mechanism. When the column 5 is fixed in the direction perpendicular to the mounting plate 2, the drive wheel 771 is first rotated in the opposite direction. At the same time, the first limiting column 772 abuts against the other second limiting column 773, so that the near hub of the cam 72 abuts against the control block 73. Under the elastic force of the first spring 74, the control block 73 moves towards the side closer to the cam 72. At the same time, the control block 73 drives one end of the two plug rods 75 to move out of the first plug groove 41 and retract into the plug hole 53, thereby releasing the fixing of the mounting column 5. Similarly, when the mounting column 5 is rotated to be parallel to the protective plate 4, the above operation is repeated so that one end of the plug rod 75 passes through the plug hole 53 and is inserted into the second plug groove 42, so that the mounting column 5 and the protective plate 4 can be fixed in the horizontal direction of the protective plate 4.

[0054] Reference Figure 1 and Figure 5 The leveling mechanism 8 includes three screws 81 threadedly connected to the base 1 below, with the three screws 81 evenly distributed along the circumference of the base 1; anti-slip blocks 82 are fixed below the screws 81. A spirit level 83 is provided above the base 1 to indicate whether the base 1 is level, thus facilitating leveling by construction personnel. A control component 84 is also provided between the screws 81 and the base 1 to control the rotation of the screws 81.

[0055] Reference Figure 5The control assembly 84 includes multiple knobs 841 mounted on the base 1, each knob 841 corresponding to a multiple screw 81. Multiple control levers 842 are fixed below each knob 841, evenly distributed circumferentially around the knob 841. A connecting ring 843 is fixed above each screw 81, and the connecting ring 843 has multiple control slots 8431 adapted to the control levers 842. The end of the control lever 842 away from the knob 841 can be inserted into the control slot 8431. A limiting block 844 is fixed on the side of the control lever 842 away from the central axis of the knob 841. A second limiting groove 55 is also provided inside the base 1, allowing both the limiting block 844 and the connecting ring 843 to slide and rotate within the second limiting groove 55. Multiple second springs 845 are provided between the connecting ring 843 and the corresponding knob 841. The multiple second springs 845 are also evenly distributed along the circumference of the knob 841, and the second springs 845 always apply a force to the knob 841 away from the screw 81. At the same time, the two ends of the second springs 845 are fixedly connected to the knob 841 and the connecting ring 843 respectively. The fixed connection of the two ends of the second springs 845 to the knob 841 and the connecting ring 843 is to ensure that even if the knob 841 is accidentally turned, it can quickly return to the initial position, so that the control rod 842 and the control groove 8431 are not easily misaligned, which facilitates the subsequent construction personnel to connect the control rod 842 and the control groove 8431.

[0056] When adjusting the base 1 to a horizontal state using the leveling mechanism 8, the operator first presses down on the knob 841. The knob 841 drives the control rod 842 to move downwards and insert into the control slot 8431, thus connecting the knob 841 with the screw 81. At the same time, the second spring 845 is further compressed. Then, the operator rotates the knob 841, which drives the screw 81 to rotate, causing the screw 81 to move away from or closer to the base 1, thereby raising or lowering one side of the mounting plate 2. Then, the operator adjusts the screws 81 to adjust the mounting plate 2 to a horizontal state. After the operator has finished adjusting, the knob 841 is released, and the knob 841 will automatically spring upwards under the action of the second spring 845. Therefore, even if the knob 841 is accidentally touched, it is not easy for the knob 841 to drive the screw 81 to rotate, thus improving the stability of the leveling mechanism 8.

[0057] This application also provides a building energy efficiency testing method, applicable to one of the above-mentioned building energy efficiency testing devices, the construction steps of which are as follows:

[0058] S1. Clean the ground on one side of the wall to be built, and place the base 1 on the ground;

[0059] S2. Rotate the drive wheel 771. The drive wheel 771 controls the fixing mechanism 7 to release the mounting column 5 from the protective plate 4. Rotate the mounting column 5 so that the mounting column 5 and the laser emitter 6 are perpendicular to the mounting plate 2. Rotate the drive wheel 771 in the opposite direction. The drive wheel 771 controls the fixing mechanism 7 to fix the mounting column 5 on the protective plate 4.

[0060] S3. Next, the installation column 5 is abutted against one side of the wall. The construction workers turn three knobs 841 respectively. The knobs 841 control the leveling mechanism 8 to level the base 1.

[0061] S4. Turn on laser emitter 6. Construction workers build the wall along the beam emitted by laser emitter 6 and observe the horizontal distance between the beam and the wall in real time.

[0062] S5. During non-construction periods, the construction personnel rotate the mounting column 5 and the laser emitter 6 into the protective cavity for storage, and fix the mounting column 5 to the protective plate 4 through the fixing mechanism 7, thereby protecting the laser emitter 6. During construction, the construction personnel repeat the above steps S2-S4 to achieve rapid start-up of the detection device.

[0063] The implementation principle of a monitoring device according to an embodiment of this application is as follows: When using the verticality monitoring device, the construction worker first places the monitoring device on the ground near the wall. Then, the construction worker rotates the drive wheel 771 to release the fixed state of the mounting column 5 and the protective plate 4. Subsequently, the construction worker rotates the mounting column 5 to make the laser emitter 6 vertical, and then rotates the drive wheel 771 in the opposite direction to fix the mounting column 5 and the protective plate 4. Then, the construction worker rotates the knob 841, which controls the screw 81 to rotate, thereby adjusting the base 1 to a horizontal state. Finally, the laser emitter 6 is turned on, which allows the detection device to start quickly during construction. Then, the construction worker builds the wall along the light beam and observes the horizontal distance between the light beam and the wall in real time. When not in use, construction workers first rotate the drive wheel 771 to release the fixing of the mounting column 5 and the protective plate 4. Then, they rotate the mounting column 5 and the laser emitter 6 into the protective cavity for storage. By rotating the drive wheel 771 in the opposite direction, the mounting column 5 and the laser emitter 6 can be fixed into the protective cavity, thus protecting the laser emitter 6. The leveling mechanism 8 can support the mounting plate 2 and keep it level. At the same time, during the construction of the wall, the construction workers can check the verticality of the wall in real time, so that it is less likely that the wall will be found to be tilted after it is built, and part of the wall will need to be demolished. This improves resource utilization and shortens the construction cycle of the wall.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
