Description

Technical Field

[0001] This application relates to the technical field of exterior wall water seepage testing, and more specifically, to a building exterior wall water seepage testing device. Background Art

[0002] After construction, the building quality needs to be tested and accepted. Among them, the exterior wall has waterproof performance requirements, and its waterproofness ensures that the exterior wall will not seep water when it rains outside. Therefore, it is necessary to conduct exterior wall water seepage testing to ensure the waterproof and anti-seepage performance of the exterior wall.

[0003] The prior art document with the publication number CN220603254U provides an exterior wall water seepage testing device, including a tabletop, a water tank arranged on the tabletop, and multiple extension rods; a feeding pipe is vertically arranged on the tabletop, and a T-shaped hole B is opened on the feeding pipe. A linear driving mechanism for driving the feeding pipe to move is installed on the tabletop. A fixed pipe is vertically arranged above the feeding pipe, and the fixed pipe is fixed on the water tank through a connecting frame. A T-shaped hole C is opened on the fixed pipe, and two clamping holes are symmetrically opened at the bottom of the fixed pipe. Clamping blocks are arranged on the outer sides of the two clamping holes. A T-shaped hole A is opened on the tabletop, and a support frame is fixed at the bottom end of the tabletop. A T-shaped lifting block is arranged above the support frame, and a water pump is installed on the water tank. By vertically splicing multiple extension rods, the installation height of the nozzle can be extended, and thus the water seepage experiment can be carried out on higher walls, with strong practicability.

[0004] Although the above prior art solution can achieve relevant beneficial effects through the structure of the prior art, there are still the following defects:

[0005] Water is directly pumped from the water tank and sprayed onto the exterior wall, and the water flow is lost as it flows down along the exterior wall. The water seepage test requires long-term continuous watering, resulting in serious waste of water resources. Moreover, the water volume in the water tank is limited and cannot meet the long-term watering requirement.

[0006] In view of the above in the related technology, the utility model person believes that water is directly pumped from the water tank and sprayed onto the exterior wall, and the water flow is lost as it flows down along the exterior wall. The water seepage test requires long-term continuous watering, resulting in serious waste of water resources. Moreover, the water volume in the water tank is limited and cannot meet the long-term watering requirement.

[0007] In view of this, we propose a building exterior wall water seepage testing device. Utility Model Content

[0008] 1. Technical Problems to be Solved

[0009] The purpose of this application is to provide a building exterior wall water seepage test device, which solves the technical problems in the above-mentioned background technology, such as directly pumping water from the water tank and spraying it onto the exterior wall, resulting in water loss as the water flows down along the exterior wall. The water seepage test requires continuous watering for a long time, which causes serious waste of water resources. Moreover, the limited water volume in the water tank cannot ensure the long-term watering requirement, and achieves the technical effect.

[0010] 2. Technical solution

[0011] The technical solution of this application provides a building exterior wall water seepage test device, comprising:

[0012] A mobile vehicle;

[0013] A water tank, which is fixedly installed on the top of the mobile vehicle;

[0014] A water collecting hopper, which is fixedly installed on the end face of the mobile vehicle;

[0015] A water discharge pipe, which is sleeved between the bottom of the water tank and the water collecting hopper;

[0016] A fixed seat, which is fixedly installed on the mobile vehicle;

[0017] A telescopic rod, which is installed on the fixed seat, and a spray head is installed on the top of the telescopic rod;

[0018] A water pump, which is fixedly installed on the fixed seat. The inlet end of the water pump is fixedly connected to a water suction pipe, and the water suction pipe extends into the inner cavity bottom of the water collecting hopper. The outlet end of the water pump is connected to the spray head through a hose.

[0019] Through the above solution, after the water tank discharges water into the water collecting hopper through the water discharge pipe, the water pump pumps the water in the water collecting hopper and sprays it onto the exterior wall through the spray head. The telescopic rod adjusts the spraying height, and the water flows continuously down along the exterior wall and is collected in the water collecting hopper for recycling, thereby saving water resources and being able to continuously water the exterior wall with limited water to achieve the test of detecting the water seepage prevention performance.

[0020] Optionally, the side of the water collecting hopper away from the mobile vehicle is of an inclined structure, and the inner cavity of the water collecting hopper is lower than the bottom height of the inner cavity of the water tank. A filter cylinder is fixedly installed at the bottom of the inner cavity of the water collecting hopper, and the water suction pipe is fixedly penetrated to the bottom of the inner cavity of the filter cylinder.

[0021] Through the above solution, the inclined end of the water collecting hopper is convenient for fitting the bottom of the exterior wall to collect the flowing-down water, saving water resources. The filter cylinder is used to fix the water suction pipe, so as to filter the returned water and then pump it.

[0022] Optionally, a valve is installed on the water discharge pipe. A fixing plate is fixedly installed on the inner wall of the water collecting hopper at the bottom of the end face of the water discharge pipe. A sliding plate is slidably clamped on the fixing plate. A sealing plate is fixedly installed on the top of the sliding plate. The sealing plate slidably fits on the inner wall of the water collecting hopper at the end face of the water discharge pipe. A floating ball is fixedly installed at the bottom of the sliding plate.

[0023] With the above solution, the opening and closing of the water discharge pipe is controlled by the valve, so that water is discharged into the water collecting hopper during the test. As the water volume in the water collecting hopper increases, the floating ball drives the sealing plate to move upward to seal the end of the water discharge pipe, preventing water from overflowing from the water collecting hopper. During the test, once the water volume decreases and the floating ball moves downward, the sealing plate exposes the water discharge pipe and automatically replenishes water to maintain the test water.

[0024] Optionally, the telescopic rod includes a fixed cylinder. The fixed cylinder is fixedly installed on the fixed seat. The bottom of the sliding cylinder is slidably clamped in the fixed cylinder. The bottom of the sliding rod is slidably clamped in the sliding cylinder. The top of the sliding rod is fixedly installed with a spray head. A plurality of clamping plates are fixedly installed on the top end faces of the fixed cylinder and the sliding cylinder. Threaded cylinders are slidably sleeved on both the sliding cylinder and the sliding rod. The threaded cylinders are threadedly connected to the outer walls of the clamping plates. The clamping plates are evenly distributed along the circumferential direction of the end faces of the fixed cylinder and the sliding cylinder. The outer walls of the clamping plates and the inner walls of the threaded cylinders are both frustum-shaped inclined structures that are smaller at the top and larger at the bottom.

[0025] With the above solution, when adjusting the watering height, loosen the threaded cylinder, then the clamping plate is loosened. At this time, the sliding rod or the sliding cylinder can be pulled to adjust the height of the spray head. Then tighten the threaded cylinder. The frustum-shaped inner wall of the threaded cylinder squeezes the clamping plate, causing the clamping plate to elastically clamp the sliding rod or the sliding cylinder inward to achieve the purpose of locking, and the adjustment is convenient.

[0026] 3. Beneficial effects

[0027] One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages:

[0028] 1. In the present application, by loosening the threaded cylinder, the clamping plate is loosened. At this time, the sliding rod or the sliding cylinder can be pulled to adjust the height of the spray head. Then tighten the threaded cylinder. The frustum-shaped inner wall of the threaded cylinder squeezes the clamping plate, causing the clamping plate to elastically clamp the sliding rod or the sliding cylinder inward to achieve the purpose of locking, thereby adjusting the watering test height;

[0029] 2. The opening and closing of the water discharge pipe is controlled by the valve, so that water is discharged into the water collecting hopper during the test. As the water volume in the water collecting hopper increases, the floating ball drives the sealing plate to move upward to seal the end of the water discharge pipe, preventing water from overflowing from the water collecting hopper. During the test, once the water volume decreases and the floating ball moves downward, the sealing plate exposes the water discharge pipe and automatically replenishes water to maintain the test water, achieving the need for water conservation while meeting the requirement of continuous watering test.

[0035] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0036] Referring to Figure 1 , an embodiment of the present application provides a building exterior wall seepage test device, comprising: a mobile vehicle 1; a water tank 2, the water tank 2 is fixedly installed on the top of the mobile vehicle 1; a water collecting hopper 3, the water collecting hopper 3 is fixedly installed on the end face of the mobile vehicle 1; a drain pipe 4, a drain pipe 4 is sleeved between the bottom of the water tank 2 and the water collecting hopper 3; a fixed seat 5, the fixed seat 5 is fixedly installed on the mobile vehicle 1; a telescopic rod 7, the telescopic rod 7 is installed on the fixed seat 5, and a sprinkler head 8 is installed on the top of the telescopic rod 7; a water pump 6, the water pump 6 is fixedly installed on the fixed seat 5, the inlet end of the water pump 6 is fixedly connected to a suction pipe 9, and the suction pipe 9 extends into the water collecting hopper 3, the outlet end of the water pump 6 is connected to the sprinkler head 8 through a hose. After the water tank 2 discharges water into the water collecting hopper 3 through the drain pipe 4, the water pump 6 pumps the water in the water collecting hopper 3 and sprays it onto the exterior wall through the sprinkler head 8. The telescopic rod 7 adjusts the spraying height, and the water flow continuously flows down along the exterior wall and is collected by the water collecting hopper 3 for recycling, so as to save water resources and be able to continuously spray water on the exterior wall with limited water to achieve the test of detecting the anti-seepage performance.

[0037] Referring to Figure 1 and Figure 2, one side of the water collecting hopper 3 away from the mobile vehicle 1 is an inclined structure, and the inner cavity of the water collecting hopper 3 is lower than the bottom height of the inner cavity of the water tank 2. A filter cylinder 10 is fixedly installed at the bottom of the inner cavity of the water collecting hopper 3. The water suction pipe 9 fixedly penetrates through to the bottom of the inner cavity of the filter cylinder 10. The inclined end of the water collecting hopper 3 is convenient for fitting the bottom of the outer wall to collect the flowing-down water, saving water resources. The filter cylinder 10 fixes the water suction pipe 9, so as to filter the returned water and then pump it out.

[0038] Refer to Figure 1 and Figure 2 , a valve is installed on the water discharge pipe 4. A fixed plate 11 is fixedly installed on the inner wall of the water collecting hopper 3 at the bottom of the end face of the water discharge pipe 4. A sliding plate 12 is slidably clamped on the fixed plate 11. A sealing plate 13 is fixedly installed at the top of the sliding plate 12. The sealing plate 13 slidably fits the inner wall of the water collecting hopper 3 at the end face of the water discharge pipe 4. A floating ball 14 is fixedly installed at the bottom of the sliding plate 12. The opening and closing of the water discharge pipe 4 are controlled by the valve, so as to discharge water into the water collecting hopper 3 during the test. And as the water volume in the water collecting hopper 3 increases, the floating ball 14 drives the sealing plate 13 to move upward to seal the end of the water discharge pipe 4, avoiding the water volume from overflowing from the water collecting hopper 3. During the test, once the water volume decreases and the floating ball 14 moves downward, the sealing plate 13 exposes the water discharge pipe 4 and automatically replenishes water to maintain the test water.

[0039] Refer to Figure 4 and Figure 3 , the telescopic rod 7 includes a fixed cylinder 71. The fixed cylinder 71 is fixedly installed on the fixed seat 5. The bottom of a sliding cylinder 72 is slidably clamped in the fixed cylinder 71. The bottom of a sliding rod 73 is slidably clamped in the sliding cylinder 72. A spray head 8 is fixedly installed at the top of the sliding rod 73. A plurality of clamping plates 74 are fixedly installed on the top end faces of the fixed cylinder 71 and the sliding cylinder 72. Threaded cylinders 75 are slidably sleeved on both the sliding cylinder 72 and the sliding rod 73. The threaded cylinders 75 are threadedly connected to the outer walls of the clamping plates 74. The clamping plates 74 are uniformly distributed along the circumferential direction of the end faces of the fixed cylinder 71 and the sliding cylinder 72. The outer walls of the clamping plates 74 and the inner walls of the threaded cylinders 75 are both frustum inclined surface structures with a smaller upper part and a larger lower part. When adjusting the watering height, loosen the threaded cylinder 75, then the clamping plate 74 is loosened. At this time, the sliding rod 73 or the sliding cylinder 72 can be pulled to adjust the height of the spray head 8. Then tighten the threaded cylinder 75. The frustum inner wall of the threaded cylinder 75 squeezes the clamping plate 74, causing the clamping plate 74 to elastically clamp the sliding rod 73 or the sliding cylinder 72 inward to achieve the purpose of locking, and the adjustment is convenient.

[0040] Working principle: The mobile vehicle 1 moves to the bottom of the test outer wall, making the water collecting hopper 3 close to the bottom of the outer wall. After the water tank 2 discharges water into the water collecting hopper 3 through the water discharge pipe 4, the water pump 6 pumps the water in the water collecting hopper 3 and sprays it onto the outer wall through the nozzle 8. Loosen the threaded cylinder 75, then the clamping plate 74 is loosened. At this time, the sliding rod 73 or the sliding cylinder 72 can be pulled to adjust the height of the nozzle 8. Then tighten the threaded cylinder 75. The conical inner wall of the threaded cylinder 75 presses against the clamping plate 74, causing the clamping plate 74 to elastically clamp the sliding rod 73 or the sliding cylinder 72 inward to achieve the locking purpose, thereby adjusting the height of the water spraying test. Control the opening and closing of the water discharge pipe 4 through the valve, so as to discharge water into the water collecting hopper 3 again during the test. And as the water volume in the water collecting hopper 3 increases, the floating ball 14 drives the sealing plate 13 to move upward to seal the end of the water discharge pipe 4, preventing the water volume from overflowing from the water collecting hopper 3. During the test, once the water volume decreases and the floating ball 14 moves downward, the sealing plate 13 exposes the water discharge pipe 4 and automatically replenishes water to maintain the test water, meeting the need for continuous water spraying test while saving water.
