Description

TECHNICAL FIELD

[0001] The present application relates to the field of performance detection device for building energy-saving sound insulation material, in particular to a performance detection device for building energy-saving sound insulation material. BACKGROUND

[0002] With the increasing improvement of people's living quality, the noise between residential building floors has become the focus of attention, and the types and materials of noise reduction and sound insulation products are also increasingly rich. In the existing residential building construction process, various sound insulation materials such as sound insulation wall, sound insulation ceiling, sound insulation window and sound insulation pad are added between floors, which can effectively reduce noise propagation.

[0003] Patent No. CN221038865U discloses a detection device suitable for sound insulation material. After adding sound insulation material, the sound decibels emitted by the first detection piece hitting the sound insulation material, and the sound decibels emitted by the first detection piece hitting the ordinary partition after adding ordinary partition are compared to judge the sound insulation effect. However, when the detection work is not needed, the iron ball may be attracted by the electromagnet, which may cause the iron ball to fall off the electromagnet and hit the box, which may cause damage to the equipment in the box, thereby affecting the normal detection work in the later period. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a performance detection device for building energy-saving sound insulation material, which solves the problems raised in the background art.

[0005] To achieve the above purpose, the following technical scheme is adopted: a performance detection device for building energy-saving sound insulation material, comprising a box, a control panel is fixed on the front of the box, a support block is fixed on the top of the box, an electromotor is fixed on the side wall of the support block, the electromotor is electrically connected with the control panel, an output end of the electromotor is fixed with a rotating rod, the rotating rod penetrates through the support block and is rotatably connected at the penetration, a winding wheel is fixed on the outer wall of the rotating rod, a support plate is slidably installed on the inner wall of the box, a pull rope is wound on the outer wall of the winding wheel, one end of the pull rope is fixed on the outer wall of the winding wheel, the other end of the pull rope is fixed on the top of the support plate, an electromagnet is fixed on the bottom of the support plate, an iron ball is attracted by the bottom of the electromagnet, a placing plate is fixed on the inner wall of the box, a noise detector is fixed on the inner wall of the placing plate, the noise detector is electrically connected with the control panel, a protection device is arranged on the support plate to prevent the iron ball from falling off, a control device is arranged on the protection device, and an auxiliary device is arranged on the top of the box. The protective device includes a connecting rod, a connecting spring, a push block, a protective cover, a hinged rod, a connecting block, a piston plate, an air chamber, a fixing block, a return spring, and a fixing frame. The connecting rod passes through the support plate and is slidably connected at the point of penetration. The top of the connecting spring is fixed to the bottom of the support plate, and the bottom of the connecting spring is fixed to the outer wall of the bottom of the connecting rod. The push block is fixed to the top of the connecting rod, and the protective cover is slidably installed on the bottom of the support plate. When the motor is started, the winding wheel winds up the pull rope, thereby driving the support plate to move upward. When the support plate drives the top of the push block to contact the top of the inner wall of the box, the push block can no longer move, and the support plate continues to move on the connecting rod, causing the connecting spring to stretch.

[0006] According to the above technical solution, the fixing block is fixed to the outer wall of the connecting rod, the connecting block passes through the side wall of the protective cover and is slidably connected at the penetration point, one end of the hinge rod is hinged to the end of the fixing block, the other end of the hinge rod is hinged to the end of the connecting block, the air chamber is opened inside the protective cover, the piston plate is slidably installed on the inner wall of the air chamber, and the side wall of the piston plate is fixedly connected to the side wall of the connecting block. According to the above technical solution, the fixing frame is fixed to the outer wall of the protective cover, one side of the return spring is fixed to the side wall of the piston plate, and the other side of the return spring is fixed to the inner wall of the fixing frame. An air vent is provided on the inner side of the protective cover, and the air vent communicates with the air chamber. When the support plate continues to move, the fixing block can press against the hinge rod, causing the hinge rod to move at the hinge point. This allows the connecting block to move the piston plate, which in turn causes the return spring to move the protective cover, thus covering the electromagnet with both sets of protective covers.

[0007] According to the above technical solution, the control device includes an iron plate, a magnet, a transmission block, a transmission plate, a transmission spring, a bending block, a limiting post, and a limiting hole. The transmission block passes through the bottom of the protective cover and is slidably connected at the penetration point. The iron plate is fixed to the top of the transmission block, the transmission plate is fixed to the bottom of the transmission block, the top of the transmission spring is fixed to the bottom of the protective cover, the bottom of the transmission spring is fixed to the top of the transmission plate, and the bending block is fixed to the side wall of the transmission plate. When the iron ball falls onto the iron plate, the weight of the iron ball can squeeze the iron plate downward, causing the transmission block to move downward, thereby driving the bending block and the limiting post to move downward and extend into the limiting hole.

[0008] According to the above technical solution, the limiting post is fixed to the outer wall of the bending block, and the top of the support plate is provided with a limiting hole.

[0009] According to the above technical solution, the auxiliary device includes a slot, a block, a return spring, a ring, a toothed block, an inclined block, a disc, an auxiliary spring, and a pressing block. The slot is formed on the outer wall of the push block, the block passes through the top of the housing and is slidably connected at the point of penetration, one side of the return spring is fixed to the inner wall of the housing, and the other side of the return spring is fixed to the side wall of the block. When the push block moves upward, it will press the inclined surface of the block, which will cause the block to move under the pressure, thus stretching the return spring.

[0010] According to the above technical solution, the ring is rotatably mounted on the side wall of the support block, the toothed blocks are arranged in multiple sets and distributed in a circumferential array on the inner wall of the ring, and the extrusion block is fixed on the outer wall of the ring.

[0011] According to the above technical solution, the disc is fixed to the outer wall of the rotating rod, the inclined block is slidably installed on the inner wall of the disc, one side of the auxiliary spring is fixed to the inner wall of the disc, and the other side of the auxiliary spring is fixed to the outer wall of the inclined block.

[0012] This invention provides a performance testing device for building energy-saving and sound-insulating materials. It has the following beneficial effects: 1. This invention, by incorporating a protective device, allows for the winding of a rope when noise detection is not required. Starting the motor causes the rotating rod to rotate clockwise, rewinding the rope and moving the support plate, electromagnet box, and iron ball upwards for resetting. When the support plate reaches a designated position, the top of the push block contacts the inner wall of the housing. As the support plate continues to move upwards, the connecting rod, fixing block, hinge rod, piston plate, reset spring, and protective covers work together to shield the electromagnet and iron ball from falling. This solves the problem of the iron ball falling and damaging the equipment inside the housing when not in use. Furthermore, the piston plate allows air to be blown out of the air chamber after the protective covers cover the iron ball, dislodging hard impurities adhering to the surface of the iron ball. This solves the problem of impurities adhering to the outer wall of the iron ball damaging the sound insulation material during noise detection. 2. This invention, through the setting of a control device, when the protective cover covers the iron ball, the iron ball loses its magnetic attraction, causing it to fall onto the iron plate. This pressure on the iron plate causes it to move downwards, which in turn moves the transmission block downwards. Through the cooperation of the transmission plate and the bending block, the limiting post can extend into the limiting hole, thus achieving the effect of limiting the protective cover. This prevents the iron ball from falling out of the protective cover when it is opened. Furthermore, when the iron plate moves downwards, it comes into contact with the magnet, causing the magnet to attract the iron plate and generate magnetic attraction. The iron ball falls onto the iron plate, where the magnetic attraction holds it in place, preventing it from rolling around. This solves the problem of the iron ball rolling off the iron plate, causing it to be out of position at the bottom of the electromagnet, making it difficult for the electromagnet to retract and return to its normal attraction.

[0013] 3. This invention, through the installation of an auxiliary device, ensures that when the support plate moves the push block to the top of the housing, the push block presses against the inclined surface of the locking block, causing the locking block to move and stretching the return spring. When the push block moves to the slot and aligns with the locking block, the return spring, in conjunction with the push block, allows the locking block to extend into the slot, effectively limiting the push block and providing secondary protection. This solves the problem of the support plate being subjected to downward impact when an iron ball accidentally falls from the electromagnet and hits the protective housing, causing the pull rope to be dragged and resulting in breakage at the connection between the pull rope and the support plate. The combination of the locking block and the slot... When the pull rope breaks due to drag, the locking block supports the push block and support plate, preventing them from falling and providing secondary protection. Furthermore, when the rotating rod drives the winding wheel to wind the pull rope, the disc, inclined block, and auxiliary spring work together to rotate the inclined surface of the inclined block on the disc against the toothed block on the inner wall of the ring, preventing the ring from rotating. When the winding wheel releases the pull rope, the plane of the inclined block presses against the plane of the toothed block, causing the ring to rotate. This forces the pressing block to push the locking block out of the slot, allowing the support plate to move downwards smoothly for normal operation of the testing equipment.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-6 One embodiment of the present invention is: a performance testing device for building energy-saving sound insulation materials, comprising a housing 1, a control panel 2 fixed to the front of the housing 1, a support block 3 fixed to the top of the housing 1, a motor 4 fixed to the side wall of the support block 3, the motor 4 being electrically connected to the control panel 2, a rotating rod 5 fixed to the output end of the motor 4, the rotating rod 5 passing through the support block 3 and being rotatably connected at the point of penetration, a winding wheel 6 fixed to the outer wall of the rotating rod 5, a support plate 8 slidably installed on the inner wall of the housing 1, and a pull rope 7 wound around the outer wall of the winding wheel 6, one end of the pull rope 7 being fixed to... The outer wall of the winding reel 6, the other end of the pull rope 7 is fixed to the top of the support plate 8, the bottom of the support plate 8 is fixed with an electromagnet 9, the bottom of the electromagnet 9 is attracted with an iron ball 14, the electromagnet 9 is electrically connected to the control panel 2, the control panel 2 can energize the electromagnet 9 so that the electromagnet 9 can attract the iron ball 14, the placement plate 15 is fixed to the inner wall of the box 1, the inner wall of the placement plate 15 is fixed with a noise detector 16, the noise detector 16 is electrically connected to the control panel 2, and the support plate 8 is provided with a protective device to prevent the iron ball 14 from falling. The protective device includes a connecting rod 101, a connecting spring 103, a push block 102, a protective cover 104, a hinge rod 105, a connecting block 108, a piston plate 107, an air chamber 106, a fixing block 109, a return spring 111, and a fixing frame 110. The connecting rod 101 passes through the support plate 8 and is slidably connected at the point of penetration. The top of the connecting spring 103 is fixed to the bottom of the support plate 8, and the bottom of the connecting spring 103 is fixed to the outer wall of the bottom of the connecting rod 101. The push block 102 is fixed to the top of the connecting rod 101. The protective cover 104 is slidably installed on the bottom of the support plate 8. The fixing block 109 is fixed to the outer wall of the connecting rod 101. The connecting block 108 passes through the side wall of the protective cover 104 and is slidably connected at the point of penetration. One end of the hinge rod 105 is hinged to the end of the fixing block 109. The other end is hinged to the end of the connecting block 108. The air chamber 106 is opened inside the protective cover 104. The piston plate 107 is slidably installed on the inner wall of the air chamber 106. The side wall of the piston plate 107 is fixedly connected to the side wall of the connecting block 108. The fixing frame 110 is fixed to the outer wall of the protective cover 104. One side of the return spring 111 is fixed to the side wall of the piston plate 107, and the other side of the return spring 111 is fixed to the inner wall of the fixing frame 110. An air outlet is opened on the inner side of the protective cover 104. The air outlet communicates with the air chamber 106. The elastic coefficient of the return spring 111 can overcome the movement of the piston plate 107 when the connecting block 108 pushes the piston plate 107 to move, so that the piston plate 107 drives the return spring 111 to move, so that the return spring 111 does not deform and drives the fixing frame 110 and the protective cover 104 to move. Two sets of protective covers 104 are provided, and the two sets of protective covers 104 are symmetrically arranged with the center line of the vertical direction of the support plate 8 as the axis of symmetry. When noise detection is not required, the motor 4 is started, and the rotating rod 5 drives the winding wheel 6 to rotate clockwise, which can wind up the pull rope 7, thereby driving the support plate 8, electromagnet 9 and iron ball 14 to move upward and reset. When the support plate 8 moves upward to the designated position, it can drive the top of the push block 102 to contact the inner wall of the box 1. When the support plate 8 continues to move upward, through the cooperation of the connecting rod 101, the fixing block 109, the hinge rod 105, the piston plate 107, the reset spring 111 and the protective cover 104, the two sets of protective covers 104 can cover the electromagnet 9 and iron ball 14 to block them, which solves the problem that when the iron ball 14 is not magnetically attracted, it will fall and damage the equipment inside the box 1. By setting the piston plate 107, the protective cover 104 can cover the iron ball 14, and the piston plate 107 can blow out the air in the air chamber 106, thereby blowing off the hard impurities attached to the surface of the iron ball 14. This solves the problem that impurities attached to the outer wall of the iron ball 14 cause damage to the sound insulation material when the iron ball 14 is dropped and noise is detected.

[0018] In this embodiment, when noise material testing is required, the door of the housing 1 is opened, the noise material is placed on the placement plate 15, the noise detector 16 is activated via the control panel 2, and the electromagnet 9 is de-energized via the control panel 2, thus eliminating the magnetic attraction of the electromagnet 9. The iron ball 14, under gravity, then strikes the noise material placed on the placement plate 15. The sound of the iron ball 14 striking the noise material is measured in decibels by the noise detector 16, and the data is transmitted to the control panel 2 for recording. After the noise material testing is completed, the ordinary... The material is placed on the placement plate 15 for testing, and the same operation as above is performed. The noise detector 16 collects the decibel data of the sound emitted by the iron ball 14 hitting the ordinary material, and then compares the data of the noisy material and the ordinary material. After the test is completed, the motor 4 is controlled to rotate the rotating rod 5 counterclockwise, which releases the pull rope 7 on the winding wheel 6, thereby driving the support plate 8 to move downward. When the support plate 8 moves downward, it drives the electromagnet 9 to move downward. The control panel 2 energizes the electromagnet 9 to generate magnetic attraction, so that when the electromagnet... When the iron ball 9 moves downwards and approaches the iron ball 14, it attracts the iron ball 14 from the test material onto the electromagnet 9, allowing for the next test. When no test is being performed, the motor 4 is controlled to rotate the rotating rod 5 clockwise, causing the winding wheel 6 to wind up the pull rope 7. This causes the pull rope 7 to move the support plate 8 upwards. As the support plate 8 moves upwards, it moves the connecting rod 101 and the push block 102 upwards. When the push block 102 moves upwards and contacts the top of the inner wall of the housing 1, the pull rope 7 continues to pull the support plate 8 upwards, causing the push block 102 to move upwards. Block 102 stops moving, causing the support plate 8 to move on the connecting rod 101, stretching the connecting spring 103. When the support plate 8 continues to move upward, it can drive the protective cover 104 to move upward, causing the protective cover 104 to drive the connecting block 108 to move upward, which will cause the hinge rod 105 to be squeezed and rotate at the hinge. This will cause the connecting block 108 to push the piston plate 107, causing the piston plate 107 to drive the return spring 111 to move, allowing the return spring 111 to drive the fixed frame 110 and the two sets of protective covers 104 to move closer to each other, covering the iron ball 14.When the two sets of protective covers 104 come close together, as the support plate 8 continues to move on the connecting rod 101, the connecting block 108 pushes the piston plate 107 to move in the air chamber 106, allowing the piston plate 107 to squeeze the gas in the air chamber 106 out and discharge it through the air outlet, blowing away impurities attached to the outer wall of the iron ball 14. When the piston plate 107 moves, the return spring 111 is stretched. When inspection is required, the motor 4 is started, causing the rotating rod 5 to drive the winding wheel 6 to rotate counterclockwise, thereby releasing the pull rope 7 and allowing the support plate 8 to move downwards. The movement of the spring 103 causes the protective cover 104 to move downwards, which in turn causes the support plate 8 to move the push block 102 downwards. Because the connecting spring 103 is in a stretched state, the position between the support plate 8 and the push block 102 is reset. Furthermore, through the cooperation of the fixing block 109 and the hinge rod 105, the connecting block 108 is reset, causing the connecting block 108 to move the piston plate 107 and the fixing frame 110. This pulls the two sets of protective covers 104 away from each other, resetting them. When the piston plate 107 is resetting in the air chamber 106, it can draw external gas into the air chamber 106 for the next blowing operation.

[0019] Please see Figures 1-6 Based on the above embodiments, in another embodiment of the present invention, a control device is provided on the protective device, and an auxiliary device is provided on the top of the housing 1. The control device includes an iron plate 122, a magnet block 128, a transmission block 121, a transmission plate 124, a transmission spring 123, a bending block 125, a limiting post 126, and a limiting hole 127. The transmission block 121 passes through the bottom of the protective cover 104 and is slidably connected at the penetration point. The iron plate 122 is fixed to the top of the transmission block 121, the transmission plate 124 is fixed to the bottom of the transmission block 121, the top of the transmission spring 123 is fixed to the bottom of the protective cover 104, the bottom of the transmission spring 123 is fixed to the top of the transmission plate 124, the bending block 125 is fixed to the side wall of the transmission plate 124, the limiting post 126 is fixed to the outer wall of the bending block 125, and a limiting hole 127 is provided on the top of the support plate 8.

[0020] When the protective cover 104 covers the iron ball 14, the iron ball 14 loses its magnetic attraction and falls onto the iron plate 122, squeezing the iron plate 122 and causing it to move downwards. This causes the transmission block 121 to move downwards. Through the cooperation of the transmission plate 124 and the bending block 125, the limiting post 126 can be inserted into the limiting hole 127, thereby achieving the limiting effect of the protective cover 104. To prevent the iron ball 14 from falling into the protective cover 104, causing it to fall out when the protective cover 104 is opened; and to prevent the iron plate 122 from contacting the magnet 128 when it moves downwards, causing the magnet 128 to attract the iron plate 122, thus generating a magnetic force on the iron plate 122, causing the iron ball 14 to fall onto the iron plate 122 and be attracted by the magnetic force on the iron plate 122, preventing the iron ball 14 from rolling around on the iron plate 122. This solves the problem that when the iron ball 14 rolls on the iron plate 122, causing it to be out of position at the bottom of the electromagnet 9, it becomes difficult for the electromagnet 9 to retract and reposition the iron ball 14 when its attraction returns to normal.

[0021] The auxiliary device includes a slot 131, a locking block 132, a return spring 133, a ring 134, a toothed block 135, an inclined block 138, a disc 137, an auxiliary spring 139, and a pressing block 136. The slot 131 is formed on the outer wall of the push block 102, the locking block 132 passes through the top of the housing 1 and is slidably connected at the passage, one side of the return spring 133 is fixed to the inner wall of the housing 1, and the other side of the return spring 133 is fixed to the side wall of the locking block 132. The ring 134 is rotatably mounted on the side wall of the support block 3. Multiple sets of toothed blocks 135 are arranged in a circumferential array on the inner wall of the ring 134. The pressing block 136 is fixed on the outer wall of the ring 134. The disc 137 is fixed on the outer wall of the rotating rod 5. The inclined block 138 is slidably mounted on the inner wall of the disc 137. One side of the auxiliary spring 139 is fixed on the inner wall of the disc 137, and the other side of the auxiliary spring 139 is fixed on the outer wall of the inclined block 138.

[0022] When the support plate 8 moves the push block 102 to the top of the box 1, the push block 102 will press against the inclined surface of the locking block 132, causing the locking block 132 to move and drive the return spring 133 to stretch. When the push block 102 moves to the slot 131 and aligns with the locking block 132, the locking block 132 can be inserted into the slot 131 through the cooperation of the return spring 133, which has the effect of limiting the push block 102 and providing secondary protection. This solves the problem that when the iron ball 14 accidentally falls from the electromagnet 9 and hits the protective box, the support plate 8 will be subjected to downward impact, dragging the pull rope 7 and causing the connection between the pull rope 7 and the support plate 8 to break. Through the cooperation of the locking block 132 and the slot 131, when the pull rope 7 is dragged and breaks, the locking block 132 can support the push block 102 and the support plate 8 to prevent it from falling, thus achieving the effect of secondary protection. When the rotating rod 5 drives the winding wheel 6 to wind the pull rope 7, the inclined surface of the inclined block 138 on the disc 137 rotates on the toothed block 135 on the inner wall of the ring 134 through the cooperation of the disc 137, the inclined block 138, and the auxiliary spring 139, so that the ring 134 does not rotate. When the winding wheel 6 releases the pull rope 7, the plane of the inclined block 138 will press against the plane of the toothed block 135, causing the ring 134 to rotate. This will allow the pressing block 136 to press the locking block 132 out of the locking groove 131, so that the support plate 8 can move downward smoothly and the testing equipment can be used normally.

[0023] In this embodiment, when the protective cover 104 covers the iron ball 14 and the electromagnet 9, if the magnetic force of the electromagnet 9 suddenly decreases, causing instability in the attraction of the iron ball 14, the iron ball 14 will fall off the electromagnet 9 and land on the iron plate 122. The iron ball 14 will then press against the iron plate 122, causing it to move downwards. This movement drives the transmission block 121 downwards, which in turn moves the transmission plate 124 downwards. As the transmission plate 124 moves downwards, it stretches the transmission spring 123. Simultaneously, the downward movement of the transmission plate 124 drives the bending block 125 downwards, causing the limiting post 126 to move downwards. Because the two sets of protective covers 104 come close together, the limiting post 126 aligns with the limiting hole 127. As the limiting post 126 moves downwards, it extends into the limiting hole 127, thus limiting the movement of the protective cover 104. When the iron plate 122 moves downward, its bottom contacts the top of the magnet 128, creating a magnetic attraction. When the iron ball 14 falls onto the iron plate 122, the magnetic attraction keeps it in place, causing it to adhere to the electromagnet 9's attraction range. When the electromagnet 9 regains its magnetic attraction, its magnetic force is ten times that of the magnet 128, allowing it to hold the iron ball 14 in place. When the iron ball 14 is attracted to the electromagnet 9, it does not squeeze the iron plate 122. Because the spring force coefficient of the transmission spring 123 is greater than the magnetic attraction force of the magnet 128, the transmission spring 123 can drive the transmission plate 124 and the transmission block 121 to move upward to reset, and the limiting post 126 moves out of the limiting hole 127, thereby releasing the limitation on the protective cover 104, and allowing the two sets of protective covers 104 to move away from each other for detection operations. Furthermore, when the equipment is not in use, when the support plate 8 moves the push block 102 upward and contacts the inner wall of the housing 1, the top of the push block 102 will first press against the inclined surface of the locking block 132. Since the elastic coefficient of the connecting spring 103 is five times that of the return spring 133, when the push block 102 presses against the inclined surface of the locking block 132, the locking block 132 can be moved, causing the return spring 133 to stretch. And when the push block 102 moves upward to the slot... When 131 is aligned with the limiting hole 127, the return spring 133 is in a stretched state, which can drive the locking block 132 to extend into the push block 102 to limit the push block 102; it can also limit the support plate 8 to prevent the support plate 8 from falling off the pull rope 7; and when the inspection operation is to be carried out, when the motor 4 controls the rotating rod 5 to rotate counterclockwise, the rotating rod 5 can drive the disc 137 to rotate counterclockwise, which will cause the inclined block to... The plane of 138 presses against the plane of the toothed block 135, thereby driving the ring 134 to rotate. This causes the pressing block 136 on the outer wall of the ring 134 to press against the locking block 132, allowing the locking block 132 to move out of the locking slot 131. Furthermore, because the winding wheel 6 rotates counterclockwise, the pull rope 7 will loosen from the winding wheel 6. Therefore, when the push block 102 is released from its limit, the support plate 8 will cause the push block 102 to fall downwards. And when the motor 4 controls the winding wheel 6 to rotate clockwise... When the needle rotates and winds up the pull rope 7, the disc 137 causes the inclined block 138 to rotate clockwise, which in turn causes the inclined surface of the inclined block 138 to press against the inclined surface of the tooth block 135. The spring force coefficient of the return spring 133 is five times that of the auxiliary spring 139. Because the inclined block 138 is compressed and moves into the disc 137, the auxiliary spring 139 is compressed. Therefore, when the inclined block 138 rotates clockwise, it does not cause the ring 134 to rotate.
