A top plate 704 is fixedly installed on the top of the support rod 703, and a panel 705 with scales is vertically arranged on the side of the top plate 704, and a slide groove 713 is vertically arranged on the panel 705. A slider 709 is slidably installed in the slide groove 713, and the slider 709 is fixedly connected to a pointer 707 through a connecting block 708. The pointer 707 is arranged on the side of the panel 705 with the scale. A pulley 715 is arranged below the top plate 704, and the float 711 is connected to the slider 709 by a pull rope 710. The pull rope 710 is wound around the pulley 715, and a retractable wire device for retracting and releasing the pull rope 710 is arranged in the slider 709.

[0034] Among them, the base 1 is round or square, and the base 1 contacts the road surface to be tested during use. In order to facilitate manufacturing and processing, the base 1 is preferably round; the support plate 2 is round or square, and is used to install the measuring cylinder 701. In order to facilitate manufacturing and processing, the support plate 2 is preferably round. In order to ensure stability, the diameter of the base 1 must be larger than the diameter of the support plate 2. The base 1 and the support plate 2 are connected by a connecting pipe 4. The connection between the connecting pipe 4 and the base 1 and the support plate 2 can be bonded or screwed. In order to ensure airtightness, when screw connection is adopted, a sealing ring is required to be used for sealing at the connection; the drain hole 14 is a circular hole, which can be manufactured and processed by an electric drill; the measuring cylinder 701 is vertically arranged above the support plate 2. The connection between the measuring cylinder 701 and the support plate 2 can be bonded or screwed. If screw connection is adopted, it is also necessary to use a sealing ring at the connection. The measuring cylinder 701 is connected with the connecting pipe 4, and the connecting pipe 4 is connected with the drain hole 14. When water is added to the measuring cylinder 701, the water will flow into the connecting pipe 4 through the measuring cylinder 701, and then flow into the road surface to be tested from the drain hole 14 through the connecting pipe 4. A switch valve 5 is installed on the connecting pipe 4. The switch valve 5 can adopt a ball valve or a structure similar to a faucet switch. A float 711 is set in the measuring cylinder 701. The diameter of the float 711 is smaller than the inner diameter of the measuring cylinder 701, and the float 711 will float on the water surface.

[0035] The sleeve rod 702 is a round rod or a square rod with an open upper end. The lower end of the sleeve rod 702 is bonded or bolted to the support plate 2. The sleeve rod 702 is arranged on both sides of the measuring cylinder 701. During manufacturing, the sleeve rod 702 is ensured to be symmetrical to the axis of the measuring cylinder 701 as much as possible. The support rod 703 is used in conjunction with the sleeve rod 702. The support rod 703 and the sleeve rod 702 can be connected by a dovetail groove and a dovetail block, or the support rod 703 is directly inserted into the sleeve rod 702. When the height needs to be adjusted, the support rod 703 is moved up and down relative to the sleeve rod 702 by manpower; the locking mechanism 712 is used to lock the support rod 703 on the sleeve rod 702, a threaded through hole is made on the sleeve rod 702, and a bolt is screwed into the threaded through hole until the end of the bolt contacts the outer surface of the support rod 703, so as to lock the support rod 703; the support rod 703 and the sleeve rod 702 can also be connected by a screw rod, and the sleeve rod 702 is connected to the support rod 703. A threaded rod is manufactured at the end, and a threaded hole is manufactured at the lower end of the support rod 703. The rotation between the support rod 703 and the sleeve rod 702 is used to realize the relative movement of the support rod 703 and the sleeve rod 702. At the same time, the self-locking of the thread can also realize the locking between the support rod 703 and the sleeve rod 702; the top plate 704 is a rectangular plate, which is respectively connected to the tops of the two support rods 703. The top plate 704 and the support rods 703 can be connected by bolts or bonding; a panel 705 is installed on the side of the top plate 704. The side of the top plate 704 refers to the surface where the long side of the top plate 704 is located. The connection method of the panel 705 and the top plate 704 can be bolted or clamped.A slide groove 713 is vertically arranged on the panel 705, and a slider 709 is slidably installed in the slide groove 713. The slider 709 is fixedly connected to a pointer 707 through a connecting block 708. The pointer 707 is arranged on the side of the panel 705 with scales. A pulley 715 is arranged below the top plate 704. The floating ball 711 and the slider 709 are connected by a pull rope 710; the pull rope 710 is wound around the pulley 715; in this way, the floating ball 711, the pulley 715 and the slider 709 form a pulley 715 structure. When the floating ball 711 moves up and down, the pull rope 710 will drive the slider 709 to move up and down, and then indicate it on the panel 705 with scales through the pointer 707; a pull rope 710 is arranged inside the slider 709 for retracting and releasing the pull rope 71 0's wire-retracting and -unwinding device, the function of which is to control the length of the pull rope 710, the wire-retracting and -unwinding device can use a drum plus a worm gear structure, a worm gear is installed on the shaft of the drum, a worm gear for matching is installed below the worm gear, the worm gear is rotated to drive the worm gear to rotate, and then the drum is driven to rotate, and the end of the pull rope 710 is fixed on the drum when in use, when the support rod 703 moves upward relative to the sleeve rod 702, in order to enable the pointer 707 to point to the zero scale of the panel 705, the worm gear is rotated forward to extend the length of the pull rope 710; similarly, when the support rod 703 moves downward relative to the sleeve rod 702, in order to enable the pointer 707 to point to the zero scale of the panel 705, the worm gear is rotated backward to shorten the length of the pull rope 710.

[0036] For further information, see Figure 4 The wire retracting and releasing device includes a wire roller 805 rotatably installed inside a slider 709, one end of the pull rope 710 is wound around the wire roller 805, a rotating shaft 803 of the wire roller 805 extends to the outside of the slider 709, a knob 802 is provided at the end of the rotating shaft 803, and a locking device for limiting the rotation of the wire roller 805 is provided on the slider 709.

[0037] Among them, baffles 804 are coaxially arranged at both ends of the line roller 805, and the height of the baffle 804 determines how much of the pull rope 710 can be retracted. One end of the pull rope 710 is wound around the line roller 805, and the rotating shaft 803 of the line roller 805 extends to the outside of the slider 709. A knob 802 is arranged at the end of the rotating shaft 803. By turning the knob 802, the line roller 805 is driven to rotate, so that the pull rope 710 can be retracted and released; when the line roller 805 is retracted and released, it is necessary to lock the line roller 805. The locking device can use a bolt, and a threaded hole is made on the slider 709, and the bolt is screwed into the threaded hole until the end of the bolt contacts the line roller 805, thereby achieving the locking of the line roller 805.

[0038] The bolt is used for locking, and the bolt needs to be screwed in and out continuously during use, which is inconvenient to use. For further information, see Figure 4The limiting device includes a pressure rod 801 located above the line roller 805. There are two pressure rods 801, which are respectively arranged on two side plates of the slider 709 along the axis of the line roller 805. One end of the pressure rod 801 extends to the outside of the slider 709. A connecting spring 806 is arranged between the pressure rod 801 and the side plate. A brake block 810 is arranged at the bottom of the pressure rod 801, and the end of the brake block 810 is opposite to the baffle 804 of the wire wheel.

[0039] The pressure rod 801 is in the shape of a square frame and includes four sides. Two through holes are respectively made on the two side plates of the slider 709. One side of the pressure rod 801 is disassembled, and the two sides of the pressure rod 801 are inserted into the through hole. After the insertion, the disassembled side is installed. A connecting spring 806 is arranged between the pressure rod 801 and the side plate. When the pressure rod 801 is pushed to move inside the slider 709, the connecting spring 806 is stretched. After being released, the connecting spring 806 automatically resets. A brake block 810 is arranged, and the end of the brake block 810 is opposite to the baffle 804 of the wire wheel. The brake block 810 and the pressure rod 801 can be connected by integral molding or bolt connection. The brake block 810 is "L"-shaped. When the connecting spring 806 is stretched, the brake block 810 is away from the baffle 804, so that the wire roller 805 can rotate. When the connecting spring 806 is reset, the brake block 810 is close to the baffle 804, contacts with the baffle 804, and locks the wire roller 805.

[0040] When the brake block 810 contacts the baffle 804, the friction force is used to lock the line roller 805. Figure 4 and Figure 6 The baffle plate 804 is provided with a wheel groove 811 for use with the end of the brake block 810. A plurality of wheel grooves 811 are provided, and are arranged along the circumference of the baffle plate 804. When in use, the brake block 810 is inserted into the wheel groove 811 to achieve the locking of the line roller 805. The wheel groove 811 can avoid the relative sliding between the brake block 810 and the line roller 805 due to insufficient friction.

[0041] When the brake block 810 is damaged, the wire roller 805 can rotate freely, resulting in the inability to properly reel in and release the wire, and the pointer 707 will always point to the zero scale line. Figure 4 and Figure 5A first clamping portion 808 is provided on one of the pressure rods 801, and a second clamping portion 809 is provided on the other pressure rod 801. The pull rope 710 passes between the first clamping portion 808 and the second clamping portion 809. The two first clamping portions 808 and the second clamping portions 809 form a clamping mechanism for clamping or loosening the pull rope 710. The first clamping part 808 and the pressure rod 801 can be connected in an integrated manner or by bonding, and the second clamping part 809 and another pressure rod 801 can be connected in an integrated manner or by bonding. The first clamping part 808 can be formed of two first U-shaped frames, and the second clamping part 809 can be formed of one second U-shaped frame, and the second U-shaped frame is placed between the two first U-shaped frames. When the two pressure rods 801 move relative to each other, a gap appears between the first clamping part 808 and the second clamping part 809, and the pull rope 710 can move up and down between the first clamping part 808 and the second clamping part 809. When the two pressure rods 801 are reset, the edges of the first clamping part 808 and the second clamping part 809 overlap, and the pull rope 710 is pressed to achieve the clamping of the pull rope 710. Similarly, the first clamping part 808 can be formed of two triangular frames, and the second clamping part 809 can be formed of one triangular frame. The use process is the same as that of the U-shaped frame, which will not be repeated here.

[0042] In order to improve the stability of the entire device, the contact area between the base 1 and the ground is increased. Figure 1 and Figure 8 An auxiliary support assembly 6 is provided on the base 1, and the auxiliary support assembly 6 includes a sliding groove 605 opened at the bottom of the base 1 along the circumference of the base 1, and a through groove 604 is opened at the top of the base 1 above the sliding groove 605, and the through groove 604 is connected with the sliding groove 605. An extension plate 601 is slidably provided in the sliding groove 713, and a ring 603 is slidably sleeved on the connecting pipe 4. A butterfly bolt is provided between the ring 603 and the connecting pipe 4, and the extension plate 601 and the ring 603 are hinged through a diagonal support rod 602.

[0043] The connection between the extension plate 601 and the sliding groove 605 can be achieved by slidingly matching the dovetail groove and the dovetail block, that is, the sliding groove 605 is a dovetail groove, and a dovetail block matching the dovetail groove is manufactured or connected on the extension plate 601, so that the extension plate 601 can slide relative to the sliding groove 605; a through groove 604 is provided above the sliding groove 605, and the length of the through groove 604 is less than the length of the sliding groove 605; when in use, the collar 603 is slid downward along the connecting pipe 4, and the collar 603 pushes the side diagonal support rod 60 downward 2. The diagonal support rod 602 passes through the through slot 604 to push the extension plate 601 to move outward along the sliding slot 605, so that the extension plate 601 can be extended from the base 1, which can increase the contact area between the base 1 and the road surface to be detected, thereby making the device more stable. In order to avoid free movement between the collar 603 and the connecting pipe 4, a threaded hole can be made on the collar 603, and the collar 603 can be locked with a butterfly bolt. When not in use, the collar 603 can be moved in the opposite direction to retract the extension plate 601 and reduce the space occupied.

[0044] In order to further improve the stability of the support plate 2, see Figure 1 and Figure 2 A support rod 3 is provided between the base 1 and the support plate 2, and the support rod 3 is arranged along the circumference of the connecting pipe 4. The support rod 3 and the base 1 and the support plate 2 can be bolted or bonded, and a plurality of support rods 3 can be provided and arranged along the circumference of the connecting pipe 4.

[0045] During use, as the water level in the measuring cylinder 701 continues to drop, the pointer 707 also continues to move, which makes it difficult for the measurement personnel to read the reading. Figure 3 and Figure 7 , mounting grooves 714 are provided on both sides of the slide groove 713, and an electromagnet 10 is fixedly installed in the mounting groove 714, iron sheets are fixedly connected on both sides of the connection block 708, and the connection block 708 is in contact with the surface of the electromagnet 10, and a battery 13 for powering the electromagnet 10 is provided on the top of the panel 705, and a switch 12 for cutting off or opening the electrical connection between the battery 13 and the electromagnet 10 is also provided on the panel 705. During use, when reading is required, the switch 12 is pressed, the electromagnet is energized to generate magnetic force to attract the iron sheet, the slider 709 stops moving, and the pointer 707 also stops moving up and down, so that the measurement personnel can read the current value very conveniently.

[0046] In order to improve the stability of the entire device, further see Figure 2 , a counterweight 9 is installed on the support plate 2. The counterweight 9 is a large iron block, which can be directly placed above the support plate 2 when in use, or can be glued to the support plate 2 using double-sided adhesive.

[0047] Although the drain hole 14, the connecting pipe 4 and the measuring cylinder 701 are connected, if they are not arranged on the same axis, the water may flow down from the measuring cylinder 701 at a slower speed. Figure 1 The drainage hole 14, the connecting pipe 4 and the measuring cylinder 701 are coaxially arranged.

[0048] The working process of the present invention is as follows: when in use, a sealing coating is applied to the edge of the detection position of the bridge pavement, and then the base 1 is tightly attached to the top of the sealing coating, the locking mechanism 712 is loosened, the support rod 703 is adjusted to a suitable position, and then the support rod 703 is locked on the sleeve rod 702, and then the length of the pull rope 710 is adjusted by the retracting and releasing device, and then water is injected into the measuring cylinder 701 so that the water flows into the drain hole 14 of the base 1 to discharge the air, and then the switch valve 5 can be closed, and the measuring cylinder 701 is filled with water, and then the switch valve 5 is opened again, and when the water level drops to the specified scale, the stopwatch is immediately used for timing, and in the process of water seeping into the bridge deck, the float 711 floats on the water surface, and As the water level inside the measuring cylinder 701 drops, the float 711 will also drop synchronously. During the descent of the float 711, the slider 709 is driven upward along the slide groove 713 by the pull rope 710, thereby driving the pointer 707 to move upward. The distance moved by the pointer 707 is the height of the drop of the water level inside the measuring cylinder 701. The button switch 12 is pressed every one minute to energize the electromagnet 10 so that the electromagnet 10 can generate magnetic force, thereby adsorbing the slider 709 and preventing the slider 709 from moving further. At this time, the position of the pointer 707 remains stationary, which is convenient for recording data. The height of the water level drop is recorded by the change of the scale pointed by the pointer 707, which is convenient for the detection personnel to accurately collect data.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
